Title: Ultraproducts - they aren't just for logicians<br />
<br />
Abstract: If any of you have attended a logic talk (or one of Ivan's donut seminar talks) you may have learned about ultraproducts as a weird way to mash sets together to get bigger sets in a nice way. Something particularly useful to set theorists, but maybe not so obviously useful to the rest of us. I will give an accessible introduction to ultraproducts and motivate their use in other areas of mathematics.<br />

Title: Fun with Hamel Bases!<br />
<br />
Abstract: If we view the real numbers as a vector field over the rationals, then of course they have a basis (assuming the AOC). This is called a Hamel basis and allows us to do some cool things. Among other things, we will define two periodic functions that sum to the identity function.<br />

Title: Practical Graph Isomorphism<br />
<br />
Abstract: Some graphs are different and some graphs are the same. Sometimes graphs differ only in name. When you give me a graph, you've picked an order. But, is it the same graph across every border?<br />

Title: Strichartz Estimates from Qualitative to Quantitative<br />
<br />
Abstract: Strichartz estimates are inequalities that give one way understand the decay of solutions to dispersive PDEs. This talk is an attempt to reconcile the formal statements with physical intuition.<br />

<br />
'''Who:''' YOU!!<br />
<br />
'''Why:''' The purpose of this seminar is to learn algebraic geometry by giving and listening to talks in a informal setting. Talks are typically accessible to beginning graduate students and take many different forms. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Friday Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth.<br />
<br />
'''How:'''If you want to get emails regarding time, place, and talk topics ('''which are often assigned quite last minute''') add yourself to the gags mailing list: gags@lists.wisc.edu. The list registration page is [https://admin.lists.wisc.edu/index.php?p=11&l=gags here].<br />
'''<br />
<br />
<br />
<br />
<br />
<br />
== Give a talk! ==<br />
We need volunteers to give talks this semester. If you're interested contact [mailto:djbruce@math.wisc.edu DJ], or just add yourself to the list (though in that case we might move your talk later without your permission). Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.<br />
<br />
<br />
== Wish List ==<br />
If there is a subject or a paper which you'd like to see someone give a talk on, add it to this list. If you want to give a talk and can't find a topic, try one from this list.<br />
<br />
* Sheaf operations on D-modules (the point is that then you can get a Fourier-Mukai transform between certain O-modules and certain D-modules, which is more or less how geometric Langlands is supposed to work)<br />
<br />
* A careful explanation of the correspondence between graded modules and sheaves on projective varieties.<br />
<br />
* Braverman and Bezrukavnikov: geometric Langlands correspondence for D-modules in prime characteristic: the GL(n) case (Note: this title sounds tough but prime characteristic makes things ''easier'')<br />
<br />
* Homological projective duality<br />
<br />
* The orbit method (for classifying representations of a Lie group)<br />
<br />
* Kaledin: geometry and topology of symplectic resolutions<br />
<br />
* Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)<br />
<br />
* Geometric complexity theory, maybe something like arXiv:1508.05788.<br />

|-<br />
| bgcolor="#BCD2EE" | <br />
Abstract: Previously we discussed the basic definitions of tropical geometry, and<br />
the connection to algebraic geometry. Now we use this to count curves<br />
through points on P^2. This is a well known result initially proven<br />
without the use of tropical tools. But using tropical tools we can give<br />
a proof that relies on the combinatorics of lattice paths. I will begin<br />
with a review of some facts from tropical geometry that we need for this<br />
proof. <br />

Abstract: I will explain in what sense we now "know" the derived category of projective space from Beilinson's result. There is a very nice answer in terms of quivers but I got distracted by another, much less efficient but maybe more flexible approach using dg categories, so that is what we will do. If my understanding permits, we will also talk about the derived category of a projective space bundle.<br />

|-<br />
| bgcolor="#BCD2EE" | <br />
Abstract: While the Bezout bound generically gives us the number of roots of a polynomial system in projective space, often much more can be said about specific systems in affine space. Kushnirenko's Theorem (and later Bernstein's theorem) gives better bounds for "sparse" systems of polynomials. These bounds are based on the volume of Newton polytopes. I will prove Kushnirenko's theorem using ideas from toric geometry, commutative algebra, and the geometry of polytopes. If time permits we will give applications of this theorem to power systems.<br />

'''Who:''' YOU!!<br />
<br />
'''Why:''' The purpose of this seminar is to learn algebraic geometry by giving and listening to talks in a informal setting. Talks are typically accessible to beginning graduate students and take many different forms. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Friday Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth.<br />
<br />
'''How:'''If you want to get emails regarding time, place, and talk topics ('''which are often assigned quite last minute''') add yourself to the gags mailing list: gags@lists.wisc.edu. The list registration page is [https://admin.lists.wisc.edu/index.php?p=11&l=gags here].<br />
'''<br />
<br />
<br />
<br />
<br />
<br />
== Give a talk! ==<br />
We need volunteers to give talks this semester. If you're interested contact [mailto:djbruce@math.wisc.edu DJ], or just add yourself to the list (though in that case we might move your talk later without your permission). Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.<br />
<br />
<br />
== Wish List ==<br />
If there is a subject or a paper which you'd like to see someone give a talk on, add it to this list. If you want to give a talk and can't find a topic, try one from this list.<br />
<br />
* Sheaf operations on D-modules (the point is that then you can get a Fourier-Mukai transform between certain O-modules and certain D-modules, which is more or less how geometric Langlands is supposed to work)<br />
<br />
* A careful explanation of the correspondence between graded modules and sheaves on projective varieties.<br />
<br />
* Braverman and Bezrukavnikov: geometric Langlands correspondence for D-modules in prime characteristic: the GL(n) case (Note: this title sounds tough but prime characteristic makes things ''easier'')<br />
<br />
* Homological projective duality<br />
<br />
* The orbit method (for classifying representations of a Lie group)<br />
<br />
* Kaledin: geometry and topology of symplectic resolutions<br />
<br />
* Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)<br />
<br />
* Geometric complexity theory, maybe something like arXiv:1508.05788.<br />

|-<br />
| bgcolor="#BCD2EE" | <br />
Abstract: Previously we discussed the basic definitions of tropical geometry, and<br />
the connection to algebraic geometry. Now we use this to count curves<br />
through points on P^2. This is a well known result initially proven<br />
without the use of tropical tools. But using tropical tools we can give<br />
a proof that relies on the combinatorics of lattice paths. I will begin<br />
with a review of some facts from tropical geometry that we need for this<br />
proof. <br />

Abstract: I will explain in what sense we now "know" the derived category of projective space from Beilinson's result. There is a very nice answer in terms of quivers but I got distracted by another, much less efficient but maybe more flexible approach using dg categories, so that is what we will do. If my understanding permits, we will also talk about the derived category of a projective space bundle.<br />

What is the liminf of the root-discriminants of all number fields? It's known (under GRH) to lie between 44.8 and 82.1. I'll explain how trying to tighten this range leads us to ask whether the 2-class tower of '''Q'''(&radic;-5460) is finite or not and I'll describe how we find ways to address this question despite repeated combinatorial explosions in the calculation. This is joint work with Jiuya Wang.<br />

Group theorists have established many formulas that express interesting properties of a finite group in terms of sums of characters of the group.

In particular, the representations of small dimension tend to contribute the largest terms to these sums, so a systematic knowledge of these small representations could lead to proofs of some of these facts.

Conductors and minimal discriminants are two measures of degeneracy of the singular fiber in a family of hyperelliptic curves. In the case of elliptic curves, the Ogg-Saito formula shows that (the negative of) the Artin conductor equals the minimal discriminant. In the case of genus two curves, equality no longer holds in general, but the two invariants are related by an inequality. We investigate the relation between these two invariants for hyperelliptic curves of arbitrary genus.<br />

What should we mean by a random algebraic number?

The tools will include variants of the Batyrev-Manin conjecture and a generalization of Siegel's theorem about integral points on curves.<br />

After A. Weil formulated Weil conjectures for Hasse-Weil zeta functions of varieties over finite fields, A. Grothendieck postulated that a reasonable cohomology theory (a good Weil cohomology) and a good understanding of algebraic cycles (e.g. the standard conjectures?) would resolve the Weil conjectures. P. Deligne’s final resolution in 1970s of the Weil conjectures however came through l-adic étale cohomology, and without resorting to the theory of algebraic cycles.<br />
<br />
In this talk, we try to shed some lights this question again from the point of view of algebraic cycles, with the slogan “Algebraic cycles should know the arithmetic” in mind. More specifically, we discuss how one can describe the de Rham-Witt complexes in terms of algebraic cycles, thus giving a algebraic-cycle theoretic description of crystalline cohomology theory.<br />

The Galois/monodromy group of a family of equations (or of a geometric problem) is a subtle invariant that encodes the structure of the solutions. In this talk, we will use numerical algebraic geometry to compute Galois groups. Our algorithm computes a witness set for the critical points of our family of equations. With this witness set, we use homotopy continuation to construct a generating set for the Galois group. Examples from classical algebraic geometry, kinematics, and formation shape control will be presented to illustrate the method. A background in algebraic geometry or numerical analysis will not be assumed. Joint work with Jonathan Haeunstein and Frank Sottile.<br />

<br />
'''Who:''' YOU!!<br />
<br />
'''Why:''' The purpose of this seminar is to learn algebraic geometry by giving and listening to talks in a informal setting. Talks are typically accessible to beginning graduate students and take many different forms. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Friday Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth.<br />
<br />
'''How:'''If you want to get emails regarding time, place, and talk topics ('''which are often assigned quite last minute''') add yourself to the gags mailing list: gags@lists.wisc.edu. The list registration page is [https://admin.lists.wisc.edu/index.php?p=11&l=gags here].<br />
'''<br />
<br />
<br />
<br />
<br />
<br />
== Give a talk! ==<br />
We need volunteers to give talks this semester. If you're interested contact [mailto:djbruce@math.wisc.edu DJ], or just add yourself to the list (though in that case we might move your talk later without your permission). Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.<br />
<br />
<br />
== Wish List ==<br />
If there is a subject or a paper which you'd like to see someone give a talk on, add it to this list. If you want to give a talk and can't find a topic, try one from this list.<br />
<br />
* Sheaf operations on D-modules (the point is that then you can get a Fourier-Mukai transform between certain O-modules and certain D-modules, which is more or less how geometric Langlands is supposed to work)<br />
<br />
* A careful explanation of the correspondence between graded modules and sheaves on projective varieties.<br />
<br />
* Braverman and Bezrukavnikov: geometric Langlands correspondence for D-modules in prime characteristic: the GL(n) case (Note: this title sounds tough but prime characteristic makes things ''easier'')<br />
<br />
* Homological projective duality<br />
<br />
* The orbit method (for classifying representations of a Lie group)<br />
<br />
* Kaledin: geometry and topology of symplectic resolutions<br />
<br />
* Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)<br />
<br />
* Geometric complexity theory, maybe something like arXiv:1508.05788.<br />

|-<br />
| bgcolor="#BCD2EE" | <br />
Abstract: Previously we discussed the basic definitions of tropical geometry, and<br />
the connection to algebraic geometry. Now we use this to count curves<br />
through points on P^2. This is a well known result initially proven<br />
without the use of tropical tools. But using tropical tools we can give<br />
a proof that relies on the combinatorics of lattice paths. I will begin<br />
with a review of some facts from tropical geometry that we need for this<br />
proof. <br />

Abstract: I will explain in what sense we now "know" the derived category of projective space from Beilinson's result. There is a very nice answer in terms of quivers but I got distracted by another, much less efficient but maybe more flexible approach using dg categories, so that is what we will do. If my understanding permits, we will also talk about the derived category of a projective space bundle.<br />

<br />
'''Who:''' YOU!!<br />
<br />
'''Why:''' The purpose of this seminar is to learn algebraic geometry by giving and listening to talks in a informal setting. Talks are typically accessible to beginning graduate students and take many different forms. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Friday Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth.<br />
<br />
'''How:'''If you want to get emails regarding time, place, and talk topics ('''which are often assigned quite last minute''') add yourself to the gags mailing list: gags@lists.wisc.edu. The list registration page is [https://admin.lists.wisc.edu/index.php?p=11&l=gags here].<br />
'''<br />
<br />
<br />
<br />
<br />
<br />
== Give a talk! ==<br />
We need volunteers to give talks this semester. If you're interested contact [mailto:djbruce@math.wisc.edu DJ], or just add yourself to the list (though in that case we might move your talk later without your permission). Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.<br />
<br />
<br />
== Wish List ==<br />
If there is a subject or a paper which you'd like to see someone give a talk on, add it to this list. If you want to give a talk and can't find a topic, try one from this list.<br />
<br />
* Sheaf operations on D-modules (the point is that then you can get a Fourier-Mukai transform between certain O-modules and certain D-modules, which is more or less how geometric Langlands is supposed to work)<br />
<br />
* A careful explanation of the correspondence between graded modules and sheaves on projective varieties.<br />
<br />
* Braverman and Bezrukavnikov: geometric Langlands correspondence for D-modules in prime characteristic: the GL(n) case (Note: this title sounds tough but prime characteristic makes things ''easier'')<br />
<br />
* Homological projective duality<br />
<br />
* The orbit method (for classifying representations of a Lie group)<br />
<br />
* Kaledin: geometry and topology of symplectic resolutions<br />
<br />
* Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)<br />
<br />
* Geometric complexity theory, maybe something like arXiv:1508.05788.<br />

|-<br />
| bgcolor="#BCD2EE" | <br />
Abstract: Previously we discussed the basic definitions of tropical geometry, and<br />
the connection to algebraic geometry. Now we use this to count curves<br />
through points on P^2. This is a well known result initially proven<br />
without the use of tropical tools. But using tropical tools we can give<br />
a proof that relies on the combinatorics of lattice paths. I will begin<br />
with a review of some facts from tropical geometry that we need for this<br />
proof. <br />

|-<br />

Abstract: I will explain in what sense we now "know" the derived category of projective space from Beilinson's result. There is a very nice answer in terms of quivers but I got distracted by another, much less efficient but maybe more flexible approach using dg categories, so that is what we will do. If my understanding permits, we will also talk about the derived category of a projective space bundle.<br />

Title: The Nottingham group<br />
<br />
Abstract: It's the group of wild automorphisms of the local field F_q((t)). It's a finitely generated pro-p group. It's hereditarily just infinite. Every finite p-group can be embedded in it. It's a favorite test case for conjectures concerning pro-p groups. It's the Nottingham group! I will introduce you to this nice pro-p group which is loved by group theorists and number theorists.<br />

Title: Who or What is the First Order & Why Should I Care?<br />
<br />
Abstract: As noted in recent films, the First Order is very powerful. We will discuss automated theorem proving software, including what exactly that means. We will then demonstrate some theorems, including previously unknown results, whose proofs can be mined from your computer.<br />
<br />
=== February 10, Jason Steinberg ===<br />
<br />
Title: Mazur's Swindle<br />
<br />
Abstract: If we sum the series 1-1+1-1+1-1+... in two ways, we get the nonsensical result 0=1 as follows: 0=(1-1)+(1-1)+(1-1)+...=1+(-1+1)+(-1+1)+...=1. While the argument is invalid in the context of adding infinitely many numbers together, there are other contexts throughout mathematics when it makes sense to take arbitrary infinite "sums" of objects in a way that these sums satisfy an infinite form of associativity. In such contexts, the above argument is valid. Examples of such contexts are connected sums of manifolds, disjoint unions of sets, and direct sums of modules, and in each case we can use this kind of argument to achieve nontrivial results fairly easily. Almost too easily...<br />
<br />
=== February 17, Zachary Charles ===<br />
<br />
Title: #P and Me: A tale of permanent complexity<br />
<br />
Abstract: The permanent is the neglected younger sibling of the determinant. We will discuss the permanent, its properties, and its applications in graph theory and commutative algebra. We will then talk about computational complexity classes and why the permanent lies at a very strange place in the complexity hierarchy. If time permits, we will discuss operations with even sillier names, such as the immanant.<br />

Title: Configuration Spaces of Graphs<br />
<br />
Abstract: A configuration of n points on a graph is just a choice of n distinct points. The set of all such configurations is a topological space, and so one can study its properties. Unsurprisingly, one can determine a lot of information about this configuration space from combinatorial data of the graph. In this talk, we consider some of the most basic properties of these spaces, and discuss how they can be applied to things like robotics. Note that most of the talk will amount to drawing pictures until everyone agrees a statement is true.<br />
<br />
=== October 14, Moisés Herradón ===<br />
<br />
Title: The natural numbers form a field<br />
<br />
Abstract: But of course, you already knew that they form a field: you just have to biject them into Q and then use the sum and product from the rational numbers. However, out of the many field structures the natural numbers can have, the one I’ll talk about is for sure the cutest. I will discuss how this field shows up in "nature" (i.e. in the games of some fellows of infinite jest) and what cute properties it has.<br />
<br />
=== October 21, David Bruce ===<br />
<br />
Title: Coverings, Dynamics, and Kneading Sequences<br />
<br />
Abstract: Given a continuous map f:X—>X of topological spaces and a point x in X one can consider the set {x, f(x), f(f(x)), f(f(f(x))),…} i.e, the orbit of x under the map f. The study of such things even in simple cases, for example when X is the complex numbers and f is a (quadratic) polynomial, turns out to be quite complex (pun sort of intended). (It also gives rise to main source of pretty pictures mathematicians put on posters.) In this talk I want to show how the study of such orbits is related to the following question: How can one tell if a (ramified) covering of S^2 comes from a rational function? No background will be assumed and there will be pretty pictures to stare at.<br />
<br />
=== October 28, Paul Tveite ===<br />
<br />
Title: Gödel Incompleteness, Goodstein's Theorem, and the Hydra Game<br />
<br />
Abstract: Gödel incompleteness states, roughly, that there are statements about the natural numbers that are true, but cannot be proved using just Peano Arithmetic. I will give a couple concrete examples of such statements, and prove them in higher mathematics.<br />
<br />
=== November 4, Wanlin Li ===<br />
<br />
Title: Expander Families, Ramanujan graphs, and Property tau<br />
<br />
Abstract: Expander family is an interesting topic in graph theory. I will define it, give non-examples and talk about the ideal kind of it, i.e. Ramanujan graph. Also, I will talk about property tau of a group and how it is related to expander families. To make the talk not full of definitions, here are part of the things I'm not going to define: Graph, regular graph, Bipartite graph, Adjacency matrix of a graph and tea...<br />
<br />
=== November 11, Daniel Hast ===<br />
<br />
Title: Scissor groups of polyhedra and Hilbert's third problem<br />
<br />
Abstract: Given two polytopes of equal measure (area, volume, etc.), can the first be cut into finitely many polytopic pieces and reassembled into the second? To investigate this question, we will introduce the notion of a "scissor group" and compute the scissor group of polygons. We will also discuss the polyhedral case and how it relates to Dehn's solution to Hilbert's third problem. If there is time, we may mention some fancier examples of scissor groups.<br />
<br />
=== November 18, James Waddington ===<br />
<br />
''Note: This week's talk will be from 3:15 to 3:45 instead of the usual time.''<br />
<br />
Title: Euler Spoilers<br />
<br />
Abstract: Leonhard Euler is often cited as one of the greatest mathematicians of the 18. Century. His solution to the Königsburg Bridge problem is an important result of early topology. Euler also did work in combinatorics and in number theory. Often his methods tended to be computational in nature (he was a computer in the traditional sense) and from these he proposed many conjectures, a few of which turned out to be wrong. Two failed conjectures of Euler will be presented.<br />
<br />
=== December 9, Brandon Alberts ===<br />

Title: The field with one element<br />

<br />
==Spring 2015==<br />
<br />
===January 28, Moisés Herradón===<br />
<br />
Title: Winning games and taking names<br />
<br />
Abstract: So let’s say we’re already amazing at playing one game (any game!) at a time and we now we need to play several games at once, to keep it challenging. We will see that doing this results in us being able to define an addition on the collection of all games, and that it actually turns this collection into a Group. I will talk about some of the wonders that lie within the group. Maybe lions? Maybe a field containing both the real numbers and the ordinals? For sure it has to be one of these two!<br />
<br />
===February 11, Becky Eastham===<br />
<br />
Title: A generalization of van der Waerden numbers: (a, b) triples and (a_1, a_2, ..., a_n) (n + 1)-tuples<br />
<br />
Abstract: Van der Waerden defined w(k; r) to be the least positive integer such that for every r-coloring of the integers from 1 to w(k; r), there is a monochromatic arithmetic progression of length k. He proved that w(k; r) exists for all positive k, r. I will discuss the case where r = 2. These numbers are notoriously hard to calculate: the first 6 of these are 1, 3, 9, 35, 178, and 1132, but no others are known. I will discuss properties of a generalization of these numbers, (a_1, a_2, ..., a_n) (n + 1)-tuples, which are sets of the form {d, a_1x + d, a_2x + 2d, ..., a_nx + nd}, for d, x positive natural numbers.<br />
<br />
===February 18, Solly Parenti===<br />
<br />
Title: Chebyshev's Bias<br />
<br />
Abstract: Euclid told us that there are infinitely many primes. Dirichlet answered the question of how primes are distributed among residue classes. This talk addresses the question of "Ya, but really, how are the primes distributed among residue classes?" Chebyshev noted in 1853 that there seems to be more primes congruent to 3 mod 4 than their are primes congruent to 1 mod 4. It turns out, he was right, wrong, and everything in between. No analytic number theory is presumed for this talk, as none is known by the speaker.<br />
<br />
===February 25, David Bruce===<br />
<br />
Title: Mean, Median, and Mode - Well Actually Just Median<br />
<br />
Abstract: Given a finite set of numbers there are many different ways to measure the center of the set. Three of the more common measures, familiar to any middle school students, are: mean, median, mode. This talk will focus on the concept of the median, and why in many ways it's sweet. In particular, we will explore how we can extend the notion of a median to higher dimensions, and apply it to create more robust statistics. It will be awesome, and there will be donuts.<br />
<br />
===March 4, Jing Hao===<br />
<br />
Title: Error Correction Codes<br />
<br />
Abstract: In the modern world, many communication channels are subject to noise, and thus errors happen. To help the codes auto-correct themselves, more bits are added to the codes to make them more different from each other and therefore easier to tell apart. The major object we study is linear codes. They have nice algebraic structure embedded, and we can apply well-known algebraic results to construct 'nice' codes. This talk will touch on the basics of coding theory, and introduce some famous codes in the coding world, including several prize problems yet to be solved!<br />
<br />

''Note: This week's seminar will be on Tuesday at 3:30 instead of the usual time.''<br />
<br />
Title: Two Solutions, not too Technical, to a Problem to which the Answer is Two<br />
<br />
Abstract: A classical problem in Algebraic Geometry is this: Given four pairwise skew lines, how many other lines intersect all of them. I will present some (two) solutions to this problem. One is more classical and ad hoc and the other introduces the Grassmannian variety/manifold and a little intersection theory.<br />
<br />
===March 25, Eric Ramos===<br />
<br />
Title: Braids, Knots and Representations<br />
<br />
Abstract: In the 1920's Artin defined the braid group, B_n, in an attempt to understand knots in a more algebraic setting. A braid is a certain arrangement of strings in three-dimensional space. It is a celebrated theorem of Alexander that every knot is obtainable from a braid by identifying the endpoints of each string. Because of this correspondence, the Jones and Alexander polynomials, two of the most important knot invariants, can be described completely using the braid group. In fact, Jones was able to show that knot invariants can often be realized as characters of special representations of the braid group.<br />
<br />
The purpose of this talk is to give a very light introduction to braid and knot theory. The majority of the talk will be comprised of drawing pictures, and nothing will be treated rigorously.<br />
<br />
===April 8, James Waddington===<br />
<br />
Title: Goodstein's Theorem<br />
<br />
Abstract: One of the most important results in the development of mathematics are<br />
Gödel's Incompleteness theorems. The first incompleteness theorem shows that no<br />
list of axioms one could provide could extend number theory to a complete and<br />
consistent theory. The second showed that one such statement was no<br />
axiomatization of number theory could be used to prove its own consistency.<br />
Needless to say this was not viewed as a very natural independent statement<br />
from arithmetic. <br />
<br />
Examples of non-metamathematical results that were independent of PA, but true<br />
of second order number theory, were not discovered until much later. Within a<br />
short time of each three such statements that were more "natural" were<br />
discovered. The Paris–Harrington Theorem, which was about a statement in Ramsey<br />
theory, the Kirby–Paris theorem, which showed the independence of Goodstein's<br />
theorem from Peano Arithmetic and the Kruskal's tree theorem, a statement about<br />
finite trees. <br />
<br />
In this talk I shall discuss Goodstein's theorem which discusses the end<br />
behavior of a certain "Zero player" game about k-nary expansions of numbers.<br />
I will also give some elements of the proof of the Kirby–Paris theorem.<br />
<br />
===April 22, William Cocke===<br />
<br />
Title: Finite Groups aren't too Square<br />
<br />
Abstract: We investigate how many non-p-th powers a group can have for a given prime p.<br />
We will show using some elementary group theory, that if np(G) is the number of non-p-th powers<br />
in a group G, then G has order bounded by np(G)(np(G)+1). Time permitting we will show this bound<br />
is strict and that mentioned results involving more than finite groups.<br />

===September 25, Vladimir Sotirov===<br />
<br />
Title: [[Media:Compact-openTalk.pdf|The compact open topology: what is it really?]]<br />
<br />
Abstract: The compact-open topology on the space C(X,Y) of continuous functions from X to Y is mysteriously generated by declaring that for each compact subset K of X and each open subset V of Y, the continous functions f: X->Y conducting K inside V constitute an open set. In this talk, I will explain the universal property that uniquely determines the compact-open topology, and sketch a pretty constellation of little-known but elementary facts from domain theory that dispell the mystery of the compact-open topology's definition.<br />
<br />
===October 8, David Bruce===<br />
<br />
Title: Hex on the Beach<br />
<br />
Abstract: The game of Hex is a two player game played on a hexagonal grid attributed in part to John Nash. (This is the game he is playing in /A Beautiful Mind./) Despite being relatively easy to pick up, and pretty hard to master, this game has surprising connections to some interesting mathematics. This talk will introduce the game of Hex, and then explore some of these connections. *As it is a lot more fun once you've actually played Hex feel free to join me at 3:00pm on the 9th floor to actually play a few games of Hex!*<br />
<br />
===October 22, Eva Elduque===<br />
<br />
Title: The fold and one cut problem<br />
<br />
Abstract: What shapes can we get by folding flat a piece of paper and making (only) one complete straight cut? The answer is surprising: We can cut out any shape drawn with straight line segments. In the talk, we will discuss the two methods of approaching this problem, focusing on the straight skeleton method, the most intuitive of the two.<br />

Title: Addition chains: To exponentiation and beyond<br />
<br />
Abstract: An addition chain is a sequence of numbers starting at one, such that every number is the sum of two previous numbers. What is the shortest chain ending at a number n? While this is already difficult, we will talk about how addition chains answer life's difficult questions, including: How do we compute 2^4? What can the Ancient Egyptians teach us about elliptic curve cryptography? What about subtraction?</div>Zcharleshttps://wiki.math.wisc.edu/index.php?title=AMS_Student_Chapter_Seminar&diff=11484AMS Student Chapter Seminar2016-02-10T22:53:07Z<p>Zcharles: </p>

Abstract: Given a continuous map f:X—>X of topological spaces and a point x in X one can consider the set {x, f(x), f(f(x)), f(f(f(x))),…} i.e, the orbit of x under the map f. The study of such things even in simple cases, for example when X is the complex numbers and f is a (quadratic) polynomial, turns out to be quite complex (pun sort of intended). (It also gives rise to main source of pretty pictures mathematicians put on posters.) In this talk I want to show how the study of such orbits is related to the following question: How can one tell if a (ramified) covering of S^2 comes from a rational function? No background will be assumed and there will be pretty pictures to stare at.<br />

Title: A generalization of van der Waerden numbers: (a, b) triples and (a_1, a_2, ..., a_n) (n + 1)-tuples<br />

I will discuss properties of a generalization of these numbers, (a_1, a_2, ..., a_n) (n + 1)-tuples, which are sets of the form {d, a_1x + d, a_2x + 2d, ..., a_nx + nd}, for d, x positive natural numbers.<br />

Abstract: In the 1920's Artin defined the braid group, B_n, in an attempt to understand knots in a more algebraic setting. A braid is a certain arrangement of strings in three-dimensional space. It is a celebrated theorem of Alexander that every knot is obtainable from a braid by identifying the endpoints of each string. Because of this correspondence, the Jones and Alexander polynomials, two of the most important knot invariants, can be described completely using the braid group. In fact, Jones was able to show that knot invariants can often be realized as characters of special representations of the braid group.<br />
<br />
The purpose of this talk is to give a very light introduction to braid and knot theory. The majority of the talk will be comprised of drawing pictures, and nothing will be treated rigorously.<br />

Title: Goodstein's Theorem<br />
<br />
Abstract: One of the most important results in the development of mathematics are<br />
Gödel's Incompleteness theorems. The first incompleteness theorem shows that no<br />
list of axioms one could provide could extend number theory to a complete and<br />
consistent theory. The second showed that one such statement was no<br />
axiomatization of number theory could be used to prove its own consistency.<br />
Needless to say this was not viewed as a very natural independent statement<br />
from arithmetic. <br />
<br />
Examples of non-metamathematical results that were independent of PA, but true<br />
of second order number theory, were not discovered until much later. Within a<br />
short time of each three such statements that were more "natural" were<br />
discovered. The Paris–Harrington Theorem, which was about a statement in Ramsey<br />
theory, the Kirby–Paris theorem, which showed the independence of Goodstein's<br />
theorem from Peano Arithmetic and the Kruskal's tree theorem, a statement about<br />
finite trees. <br />
<br />
In this talk I shall discuss Goodstein's theorem which discusses the end<br />
behavior of a certain "Zero player" game about k-nary expansions of numbers.<br />
I will also give some elements of the proof of the Kirby–Paris theorem.<br />

Title: Finite Groups aren't too Square<br />
<br />
Abstract: We investigate how many non-p-th powers a group can have for a given prime p.<br />
We will show using some elementary group theory, that if np(G) is the number of non-p-th powers<br />
in a group G, then G has order bounded by np(G)(np(G)+1). Time permitting we will show this bound<br />
is strict and that mentioned results involving more than finite groups.<br />

Title: [[Media:Compact-openTalk.pdf|The compact open topology: what is it really?]]<br />
<br />
Abstract: The compact-open topology on the space C(X,Y) of continuous functions from X to Y is mysteriously generated by declaring that for each compact subset K of X and each open subset V of Y, the continous functions f: X->Y conducting K inside V constitute an open set. In this talk, I will explain the universal property that uniquely determines the compact-open topology, and sketch a pretty constellation of little-known but elementary facts from domain theory that dispell the mystery of the compact-open topology's definition.<br />

Title: Hex on the Beach<br />
<br />
Abstract: The game of Hex is a two player game played on a hexagonal grid attributed in part to John Nash. (This is the game he is playing in /A Beautiful Mind./) Despite being relatively easy to pick up, and pretty hard to master, this game has surprising connections to some interesting mathematics. This talk will introduce the game of Hex, and then explore some of these connections. *As it is a lot more fun once you've actually played Hex feel free to join me at 3:00pm on the 9th floor to actually play a few games of Hex!*<br />

Title: The fold and one cut problem<br />
<br />
Abstract: What shapes can we get by folding flat a piece of paper and making (only) one complete straight cut? The answer is surprising: We can cut out any shape drawn with straight line segments. In the talk, we will discuss the two methods of approaching this problem, focusing on the straight skeleton method, the most intuitive of the two.<br />

Title: Addition chains: To exponentiation and beyond<br />
<br />
Abstract: An addition chain is a sequence of numbers starting at one, such that every number is the sum of two previous numbers. What is the shortest chain ending at a number n? While this is already difficult, we will talk about how addition chains answer life's difficult questions, including: How do we compute 2^4? What can the Ancient Egyptians teach us about elliptic curve cryptography? What about subtraction?</div>Zcharleshttps://wiki.math.wisc.edu/index.php?title=Main_Page&diff=10269Main Page2015-09-21T13:03:59Z<p>Zcharles: </p>

'''Who:''' YOU!!<br />
<br />
'''Why:''' The purpose of this seminar is to learn algebraic geometry by giving and listening to talks in a informal setting. Talks are typically accessible to beginning graduate students and take many different forms. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Friday Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth.<br />
<br />
'''How:'''If you want to get emails regarding time, place, and talk topics ('''which are often assigned quite last minute''') add yourself to the gags mailing list: gags@lists.wisc.edu. The list registration page is [https://admin.lists.wisc.edu/index.php?p=11&l=gags here].<br />

== Give a talk! ==<br />
We need volunteers to give talks this semester. If you're interested contact [mailto:djbruce@math.wisc.edu DJ], or just add yourself to the list (though in that case we might move your talk later without your permission). Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.<br />
<br />
<br />
== Wish List ==<br />
If there is a subject or a paper which you'd like to see someone give a talk on, add it to this list. If you want to give a talk and can't find a topic, try one from this list.<br />
<br />
* Bondal and Orlov: semiorthogonal decompositions for algebraic varieties (Note: this is about cool stuff like Fourier-Mukai transforms)<br />
<br />
* Braverman and Bezrukavnikov: geometric Langlands correspondence for D-modules in prime characteristic: the GL(n) case (Note: this title sounds tough but prime characteristic makes things ''easier'')<br />
<br />
* homological projective duality<br />
<br />
* moment map and symplectic reduction<br />
<br />
* the orbit method (for classifying representations of a Lie group)<br />
<br />
* Kaledin: geometry and topology of symplectic resolutions<br />
<br />
* Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)<br />
<br />
* geometric complexity theory, maybe something like arXiv:1508.05788.<br />

Abstract: I will introduce the techniques used by Asok and Fasel to classify rank-2 vector bundles on a smooth affine 3-fold (arXiv:1204.0770). The problem itself is interesting, and the solution uses the A^1 homotopy category. My main goal is to make this category seem less bonkers. <br />

'''Who:''' YOU!!<br />
<br />
'''Why:''' The purpose of this seminar is to learn algebraic geometry by giving and listening to talks in a informal setting. Talks are typically accessible to beginning graduate students and take many different forms. Sometimes people present an interesting paper they find. Other times people give a prep talk for the Friday Algebraic Geometry Seminar. Other times people give a series of talks on a topic they have been studying in-depth.<br />
<br />
'''How:'''If you want to get emails regarding time, place, and talk topics ('''which are often assigned quite last minute''') add yourself to the gags mailing list: gags@lists.wisc.edu. The list registration page is [https://admin.lists.wisc.edu/index.php?p=11&l=gags here].<br />
'''<br />

<br />
<br />
== Give a talk! ==<br />
We need volunteers to give talks this semester. If you're interested contact [mailto:djbruce@math.wisc.edu DJ], or just add yourself to the list (though in that case we might move your talk later without your permission). Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.<br />
<br />
<br />
== Wish List ==<br />
If there is a subject or a paper which you'd like to see someone give a talk on, add it to this list. If you want to give a talk and can't find a topic, try one from this list.<br />
<br />
* Bondal and Orlov: semiorthogonal decompositions for algebraic varieties (Note: this is about cool stuff like Fourier-Mukai transforms)<br />
<br />
* Braverman and Bezrukavnikov: geometric Langlands correspondence for D-modules in prime characteristic: the GL(n) case (Note: this title sounds tough but prime characteristic makes things ''easier'')<br />
<br />
* homological projective duality<br />
<br />
* moment map and symplectic reduction<br />
<br />
* the orbit method (for classifying representations of a Lie group)<br />
<br />
* Kaledin: geometry and topology of symplectic resolutions<br />
<br />
* Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)<br />
<br />
* geometric complexity theory, maybe something like arXiv:1508.05788.<br />

Abstract: I will introduce the techniques used by Asok and Fasel to classify rank-2 vector bundles on a smooth affine 3-fold (arXiv:1204.0770). The problem itself is interesting, and the solution uses the A^1 homotopy category. My main goal is to make this category seem less bonkers. <br />

|-<br />
| bgcolor="#BCD2EE" | <br />
Abstract: I will introduce the techniques used by Asok and Fasel to classify rank-2 vector bundles on a smooth affine 3-fold (arXiv:1204.0770). The problem itself is interesting, and the solution uses the A^1 homotopy category. My main goal is to make this category seem less bonkers. <br />

Title: Winning games and taking names<br />
<br />
Abstract: So let’s say we’re already amazing at playing one game (any game!) at a time and we now we need to play several games at once, to keep it challenging. We will see that doing this results in us being able to define an addition on the collection of all games, and that it actually turns this collection into a Group. I will talk about some of the wonders that lie within the group. Maybe lions? Maybe a field containing both the real numbers and the ordinals? For sure it has to be one of these two!<br />

Title: A generalization of van der Waerden numbers: (a, b) triples and (a_1, a_2, ..., a_n) (n + 1)-tuples<br />
<br />
Abstract: Van der Waerden defined w(k; r) to be the least positive integer such that for every r-coloring of the integers from 1 to w(k; r), there is a monochromatic arithmetic progression of length k. He proved that w(k; r) exists for all positive k, r. I will discuss the case where r = 2. These numbers are notoriously hard to calculate: the first 6 of these are 1, 3, 9, 35, 178, and 1132, but no others are known. I will discuss properties of a generalization of these numbers, (a_1, a_2, ..., a_n) (n + 1)-tuples, which are sets of the form {d, a_1x + d, a_2x + 2d, ..., a_nx + nd}, for d, x positive natural numbers.<br />

Title: Chebyshev's Bias<br />
<br />
Abstract: Euclid told us that there are infinitely many primes. Dirichlet answered the question of how primes are distributed among residue classes. This talk addresses the question of "Ya, but really, how are the primes distributed among residue classes?" Chebyshev noted in 1853 that there seems to be more primes congruent to 3 mod 4 than their are primes congruent to 1 mod 4. It turns out, he was right, wrong, and everything in between. No analytic number theory is presumed for this talk, as none is known by the speaker.<br />

<br />
Title: Mean, Median, and Mode - Well Actually Just Median<br />
<br />
Abstract: Given a finite set of numbers there are many different ways to measure the center of the set. Three of the more common measures, familiar to any middle school students, are: mean, median, mode. This talk will focus on the concept of the median, and why in many ways it's sweet. In particular, we will explore how we can extend the notion of a median to higher dimensions, and apply it to create more robust statistics. It will be awesome, and there will be donuts.<br />

===March 4, Jing Hao===<br />
<br />
Title: Error Correction Codes<br />
<br />
Abstract: In the modern world, many communication channels are subject to noise, and thus errors happen. To help the codes auto-correct themselves, more bits are added to the codes to make them more different from each other and therefore easier to tell apart. The major object we study is linear codes. They have nice algebraic structure embedded, and we can apply well-known algebraic results to construct 'nice' codes. This talk will touch on the basics of coding theory, and introduce some famous codes in the coding world, including several prize problems yet to be solved!<br />

Title: Two Solutions, not too Technical, to a Problem to which the Answer is Two<br />
<br />
Abstract: A classical problem in Algebraic Geometry is this: Given four pairwise skew lines, how many other lines intersect all of them. I will present some (two) solutions to this problem. One is more classical and ad hoc and the other introduces the Grassmannian variety/manifold and a little intersection theory.<br />

Title: Braids, Knots and Representations<br />
<br />
Abstract: In the 1920's Artin defined the braid group, B_n, in an attempt to understand knots in a more algebraic setting. A braid is a certain arrangement of strings in three-dimensional space. It is a celebrated theorem of Alexander that every knot is obtainable from a braid by identifying the endpoints of each string. Because of this correspondence, the Jones and Alexander polynomials, two of the most important knot invariants, can be described completely using the braid group. In fact, Jones was able to show that knot invariants can often be realized as characters of special representations of the braid group.<br />
<br />
The purpose of this talk is to give a very light introduction to braid and knot theory. The majority of the talk will be comprised of drawing pictures, and nothing will be treated rigorously.<br />

Title: Goodstein's Theorem<br />
<br />
Abstract: One of the most important results in the development of mathematics are<br />
Gödel's Incompleteness theorems. The first incompleteness theorem shows that no<br />
list of axioms one could provide could extend number theory to a complete and<br />
consistent theory. The second showed that one such statement was no<br />
axiomatization of number theory could be used to prove its own consistency.<br />
Needless to say this was not viewed as a very natural independent statement<br />
from arithmetic. <br />
<br />
Examples of non-metamathematical results that were independent of PA, but true<br />
of second order number theory, were not discovered until much later. Within a<br />
short time of each three such statements that were more "natural" were<br />
discovered. The Paris–Harrington Theorem, which was about a statement in Ramsey<br />
theory, the Kirby–Paris theorem, which showed the independence of Goodstein's<br />
theorem from Peano Arithmetic and the Kruskal's tree theorem, a statement about<br />
finite trees. <br />
<br />
In this talk I shall discuss Goodstein's theorem which discusses the end<br />
behavior of a certain "Zero player" game about k-nary expansions of numbers.<br />
I will also give some elements of the proof of the Kirby–Paris theorem.<br />

Title: Finite Groups aren't too Square<br />
<br />
Abstract: We investigate how many non-p-th powers a group can have for a given prime p.<br />
We will show using some elementary group theory, that if np(G) is the number of non-p-th powers<br />
in a group G, then G has order bounded by np(G)(np(G)+1). Time permitting we will show this bound<br />
is strict and that mentioned results involving more than finite groups.<br />

Title: [[Media:Compact-openTalk.pdf|The compact open topology: what is it really?]]<br />
<br />
Abstract: The compact-open topology on the space C(X,Y) of continuous functions from X to Y is mysteriously generated by declaring that for each compact subset K of X and each open subset V of Y, the continous functions f: X->Y conducting K inside V constitute an open set. In this talk, I will explain the universal property that uniquely determines the compact-open topology, and sketch a pretty constellation of little-known but elementary facts from domain theory that dispell the mystery of the compact-open topology's definition.<br />

Title: Hex on the Beach<br />
<br />
Abstract: The game of Hex is a two player game played on a hexagonal grid attributed in part to John Nash. (This is the game he is playing in /A Beautiful Mind./) Despite being relatively easy to pick up, and pretty hard to master, this game has surprising connections to some interesting mathematics. This talk will introduce the game of Hex, and then explore some of these connections. *As it is a lot more fun once you've actually played Hex feel free to join me at 3:00pm on the 9th floor to actually play a few games of Hex!*<br />

Title: The fold and one cut problem<br />
<br />
Abstract: What shapes can we get by folding flat a piece of paper and making (only) one complete straight cut? The answer is surprising: We can cut out any shape drawn with straight line segments. In the talk, we will discuss the two methods of approaching this problem, focusing on the straight skeleton method, the most intuitive of the two.<br />

Title: Addition chains: To exponentiation and beyond<br />
<br />
Abstract: An addition chain is a sequence of numbers starting at one, such that every number is the sum of two previous numbers. What is the shortest chain ending at a number n? While this is already difficult, we will talk about how addition chains answer life's difficult questions, including: How do we compute 2^4? What can the Ancient Egyptians teach us about elliptic curve cryptography? What about subtraction?</div>Zcharleshttps://wiki.math.wisc.edu/index.php?title=Math_222_Spring_2014_Lectures_1_and_2&diff=6962Math 222 Spring 2014 Lectures 1 and 22014-05-08T00:09:08Z<p>Zcharles: /* Homework solutions */</p>
