<div>= Number Theory Graduate Student Seminar, University of Wisconsin-Madison =<br />
<br />
<br />
*'''When:''' Tuesdays at 2:30pm<br />
*'''Where:''' Van Vleck Hall B105 (or possibly B129)<br />
<br />
<br><br />
<br />
The purpose of this seminar is to have a talk on each Tuesday by a graduate student to<br />
help orient ourselves for the [[NTS|Number Theory Seminar]] talk on the following Thursday.<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: Representations of reductive groups are discretely parameterized, but unipotent groups can have non-trivial families of representations, so it makes sense try to construct and understand a moduli stack (or space) of representations of a given unipotent group. If you restrict to certain kinds of representations, it is possible to actually get your hands on the moduli stack and to construct a moduli space. I'll summarize the few things I know about the general case and then give you a tour of some interesting features that appear in small examples.<br />

| bgcolor="#DDDDDD" align="center"| Title: A rationality property of Hodge cycles on abelian varieties, with an application to arithmetic compactifications of Shimura varieties<br />
|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: Let A be an abelian variety over a number field E, and let v be a finite place of E where A has bad, split, semi-stable reduction. Then the toric part of the reduction of A at v gives rise to a partial integral structure on the (l-adic, p-adic, deRham, log crystalline) cohomology group H^1(A_{E_v} ), arising essentially from the character group of the torus. Let η be a Hodge cycle on A; then one can ask if η is rational (in a precise sense) with respect to this new integral structure on the cohomology. This question was first considered by Andre ́.<br />
Using the theory of Shimura varieties and the Faltings-Chai toroidal compactifications of the moduli of principally polarized abelian varieties, we convert this question into one of deciding if a certain sub-scheme of a torus embedding is again a torus embedding. In the situation where the Mumford-Tate group of A has a reductive model over Zp, for v|p (this is the unramified situation), we employ a generalization of the methods introduced by Faltings and Kisin–initially used to construct smooth integral models of Shimura varieties–to answer this question positively.<br />
A by-product of this rationality result is the construction of good toroidal compactifications of the integral models of Shimura varieties mentioned above. This was in fact the main motivation for considering, in the first place, the possibility of such a result. A formal consequence of the existence of these compactifications is the following result, which is a slightly weakened version of a conjecture of Yasuo Morita: Suppose the Mumford-Tate group G of A is anisotropic mod center, then, for any prime p such that G admits a reductive model over Zp, A has potentially good reduction at all finite places v|p of E.<br />
The first part of the talk will be expository: we will introduce Hodge cycles on abelian varieties and their properties, so that we can state the problem at hand. Then, we will switch track and talk about the question on toric embeddings referenced above. After this, we will focus on the case where the reduction of A at v is a split torus. In this case, the theory is more combinatorial, but the key ideas for the general case are already visible. We will quickly sketch the properties that we need of Shimura varieties and the Faltings-Chai compactification, and see how they can be used to reduce the problem to the one about toric embeddings. If time remains, we will say something about how to solve this latter problem using the Faltings-Kisin method.<br />

Abstract: Modular symbol is used to construct p-adic L-functions<br />
associated to a modular form. In this talk, I will explain how to<br />
generalize this powerful tool to the construction of p-adic L-functions<br />
attached to an automorphic representation on GL_{2}(A) where A is the ring<br />
of adeles over a number field. This is a joint work with Matthew Emerton.<br />

| bgcolor="#DDDDDD"| <br />
Abstract: <br />
The family of modular curves X(p^n) provides the geometric link between two types of objects: On the one hand, 2-dimensional representations of the absolute Galois group of Q_p, and on the other, admissible representations of the group GL_2(Q_p). This relationship, known as the local Langlands correspondence, is realized in the cohomology of the modular curves. Unfortunately, the Galois-module structure of the cohomology of X(p^n) is obscured by the fact that integral models have very bad reduction. In this talk we present a new combinatorial picture of the resolution of<br />
singularities of the tower of modular curves, and demonstrate how this<br />
picture encodes some features of the local Langlands correspondence.<br />

For any elliptic curve E over Q, let N(E) and Delta(E) denote it's conductor and minimal discriminant.

In a ring of algebraic integers, the ideal class group measures the<br />
failure of unique factorization. A classical correspondence due to<br />
Dirichlet and Dedekind allows us to work with ideal classes of<br />
quadratic rings concretely in terms of binary quadratic forms with<br />
integer coefficients. A recent result of Bhargava gives an analogous<br />
correspondence between ideal classes of cubic rings and certain<br />
trilinear forms. From another point of view, the ideal class group is<br />
the group of invertible modules of a ring, whose geometric analog is<br />
the Picard group of line bundles on a space. We discuss how we can<br />
view these correspondences between ideal classes and forms<br />
geometrically, and give new results on parametrizations of ideal<br />
classes of certain rank n rings (e.g. orders in degree n number<br />
fields) by trilinear forms.<br />

| bgcolor="#DDDDDD" align="center"| On Greenberg's conjecture on derivatives of p-adic L-functions with<br />
trivial zeroes<br />
|-<br />
| bgcolor="#DDDDDD"| <br />
In 1991, Ralph Greenberg stated a conjecture about p-adic L-functions<br />
that have a trivial zero at s=1. Here "trivial" means that the zero<br />
arises from the vanishing of an Euler factor that must be removed in<br />
order to state the interpolation property of the p-adic L-function.<br />
Greenberg's conjecture concerns the value of the derivative of the<br />
p-adic L-function at s=1. An example of this conjecture is the case<br />
of the p-adic L-function of an elliptic curve E/Q with split<br />
multiplicative reduction at p. In this case, Greenberg's conjecture<br />
reduces to an earlier conjecture by Mazur, Tate, and Teitelbaum, and<br />
was proven by Greenberg himself in joint work with Glenn Stevens. In<br />
this talk, we will describe a strategy to prove new cases of<br />
Greenberg's conjecture. We will concentrate on the case of the<br />
symmetric square of an elliptic curve with good reduction at p. The<br />
strategy is a generalization of my previous work with Darmon and<br />
Pollack proving certain cases of the Gross--Stark conjecture (which<br />
can also be viewed as a special case of Greenberg's conjecture). The<br />
method involves studying explicit p-adic families of modular forms on<br />
GSp_4 and their associated Galois representations.<br />

of the p-adic L-function of an elliptic curve E/Q with split<br />
multiplicative reduction at p. In this case, Greenberg's conjecture<br />
reduces to an earlier conjecture by Mazur, Tate, and Teitelbaum, and<br />
was proven by Greenberg himself in joint work with Glenn Stevens. In<br />
this talk, we will describe a strategy to prove new cases of<br />
Greenberg's conjecture. We will concentrate on the case of the<br />
symmetric square of an elliptic curve with good reduction at p. The<br />
strategy is a generalization of my previous work with Darmon and<br />
Pollack proving certain cases of the Gross--Stark conjecture (which<br />
can also be viewed as a special case of Greenberg's conjecture). The<br />
method involves studying explicit p-adic families of modular forms on<br />
GSp_4 and their associated Galois representations.<br />

Abstract: I will describe a joint work with Barnet-Lamb, Gee and Taylor where we establish a potential automorphy result for compatible systems of Galois representations over totally real and CM fields. This is deduced from a potential automorphy result for single l-adic Galois representations satisfying a `diagonalizability' condition at the places dividing l.<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: <br />
The family of modular curves X(p^n) provides the geometric link between two types of objects: On the one hand, 2-dimensional representations of the absolute Galois group of Q_p, and on the other, admissible representations of the group GL_2(Q_p). This relationship, known as the local Langlands correspondence, is realized in the cohomology of the modular curves. Unfortunately, the Galois-module structure of the cohomology of X(p^n) is obscured by the fact that integral models have very bad reduction. In this talk we present a new combinatorial picture of the resolution of<br />
singularities of the tower of modular curves, and demonstrate how this<br />
picture encodes some features of the local Langlands correspondence.<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
For any elliptic curve E over Q, let N(E) and Delta(E) denote it's conductor and minimal discriminant. Szpiro conjecture states that for any epsilon>0, there exists a constant C such that Abs(Delta(E)) < C (N(E))^{6+\epsilon} for any elliptic curve E. This conjecture, if true, will have applications to many Diophantine equations. Assuming Szpiro conjecture, one expects that there are only finitely many semistable elliptic curves E such that min_{p|N(E)} v_p(\Delta(E)) >6. We conjecture that, in fact, there are none. In this talk we study this conjecture in some special cases, and provide some evidence towards this conjecture.<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: Classical Kloosterman sheaves are rank n local systems on<br />
the punctured line (over a finite field) which incarnate Kloosterman<br />
sums in a geometric way. The arithmetic properties of the Kloosterman<br />
sums (such as estimate of absolute values and distribution of angles)<br />
can be deduced from geometric properties of these sheaves. In this<br />
talk, we will construct generalized Kloosterman local systems with an<br />
arbitrary reductive structure group using the geometric Langlands<br />
correspondence. They provide new examples of exponential sums with<br />
nice arithmetic properties. In particular, we will see exponential<br />
sums whose equidistribution laws are controlled by exceptional groups<br />
E_7,E_8,F_4 and G_2.<br />

| bgcolor="#DDDDDD"| <br />
For any elliptic curve E over Q, let N(E) and Delta(E) denote it's conductor and minimal discriminant. Szpiro conjecture states that for any epsilon>0, there exists a constant C such that Abs(Delta(E)) < C (N(E))^{6+\epsilon} for any elliptic curve E. This conjecture, if true, will have applications to many Diophantine equations. Assuming Szpiro conjecture, one expects that there are only finitely many semistable elliptic curves E such that min_{p|N(E)} v_p(\Delta(E)) >6. We conjecture that, in fact, there are none. In this talk we study this conjecture in some special cases, and provide some evidence towards this conjecture.<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: Classical Kloosterman sheaves are rank n local systems on<br />
the punctured line (over a finite field) which incarnate Kloosterman<br />
sums in a geometric way. The arithmetic properties of the Kloosterman<br />
sums (such as estimate of absolute values and distribution of angles)<br />
can be deduced from geometric properties of these sheaves. In this<br />
talk, we will construct generalized Kloosterman local systems with an<br />
arbitrary reductive structure group using the geometric Langlands<br />
correspondence. They provide new examples of exponential sums with<br />
nice arithmetic properties. In particular, we will see exponential<br />
sums whose equidistribution laws are controlled by exceptional groups<br />
E_7,E_8,F_4 and G_2.<br />

In this talk, I will introduce equidistribution of small points in<br />
algebraic dynamical systems. The result is a corollary of the<br />
differentiability of volumes of arithmetic line bundles in Arakelov<br />
geometry. For example, the equidistribution theorem on abelian varieties<br />
by Szpiro-Ullmo-Zhang is a consequence of the arithmetic Hilbert-Samuel<br />
formula by Gillet-Soule.<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: <br />
The family of modular curves X(p^n) provides the geometric link between two types of objects: On the one hand, 2-dimensional representations of the absolute Galois group of Q_p, and on the other, admissible representations of the group GL_2(Q_p). This relationship, known as the local Langlands correspondence, is realized in the cohomology of the modular curves. Unfortunately, the Galois-module structure of the cohomology of X(p^n) is obscured by the fact that integral models have very bad reduction. In this talk we present a new combinatorial picture of the resolution of<br />
singularities of the tower of modular curves, and demonstrate how this<br />
picture encodes some features of the local Langlands correspondence.<br />

Abstract: In this talk, we will discuss (a certain form of) the<br />

Siegel-Weil formula to non-vanishing problems of theta lifts. (This is<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: Classical Kloosterman sheaves are rank n local systems on<br />
the punctured line (over a finite field) which incarnate Kloosterman<br />
sums in a geometric way. The arithmetic properties of the Kloosterman<br />
sums (such as estimate of absolute values and distribution of angles)<br />
can be deduced from geometric properties of these sheaves. In this<br />
talk, we will construct generalized Kloosterman local systems with an<br />
arbitrary reductive structure group using the geometric Langlands<br />
correspondence. They provide new examples of exponential sums with<br />
nice arithmetic properties. In particular, we will see exponential<br />
sums whose equidistribution laws are controlled by exceptional groups<br />
E_7,E_8,F_4 and G_2.<br />

Abstract: Classical Kloosterman sheaves are rank n local systems on<br />
the punctured line (over a finite field) which incarnate Kloosterman<br />
sums in a geometric way. The arithmetic properties of the Kloosterman<br />
sums (such as estimate of absolute values and distribution of angles)<br />
can be deduced from geometric properties of these sheaves. In this<br />
talk, we will construct generalized Kloosterman local systems with an<br />
arbitrary reductive structure group using the geometric Langlands<br />
correspondence. They provide new examples of exponential sums with<br />
nice arithmetic properties. In particular, we will see exponential<br />
sums whose equidistribution laws are controlled by exceptional groups<br />

non-vanishing of theta lifts from orthogonal groups<br />
|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: In this talk, we will discuss (a certain form of) the<br />
Siegel-Weil formula for the second terms (the weak second term<br />
identity). If time permits, we will give an application of the<br />
Siegel-Weil formula to non-vanishing problems of theta lifts. (This is<br />
a joint with W. Gan.)<br />

|-<br />
| bgcolor="#DDDDDD"| <br />
Abstract: Classical Kloosterman sheaves are rank n local systems on<br />
the punctured line (over a finite field) which incarnate Kloosterman<br />
sums in a geometric way. The arithmetic properties of the Kloosterman<br />
sums (such as estimate of absolute values and distribution of angles)<br />
can be deduced from geometric properties of these sheaves. In this<br />
talk, we will construct generalized Kloosterman local systems with an<br />
arbitrary reductive structure group using the geometric Langlands<br />
correspondence. They provide new examples of exponential sums with<br />
nice arithmetic properties. In particular, we will see exponential<br />
sums whose equidistribution laws are controlled by exceptional groups<br />
E_7,E_8,F_4 and G_2.<br />

'''Graduate study at UW-Madison in algebra'''<br />
<br />
Algebra is among the most popular specializations for UW Ph.D. students. Regularly offered courses include a four-semester sequence in number theory; a two-semester sequence in algebraic geometry; homological algebra; representation theory; advanced topics in group theory. We also regularly offer more advanced topics courses, which in recent years have included the Gross-Zagier formula, classification of algebraic surfaces, and p-adic Hodge theory. Here is [http://www.math.wisc.edu/gcourses_fall a list of this fall's graduate courses].<br />
<br />
The department holds an [http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=0838210&version=noscript NSF-RTG grant in number theory and algebraic geometry], which funds several research assistantships for graduate students (U.S. citizens and permanent residents) working in those areas. <br />
<br />
Recent Ph.D. graduates from the group have been very successful on the job market; in the last few years, we have sent alumni to postdoctoral fellowships at Berkeley, Harvard, Imperial (UK), MIT, Princeton, Stanford, and UT-Austin, to tenure-track jobs at McGill, Wake Forest, Bucknell, the University of New Mexico, and the University of South Carolina, and to non-academic positions at places such as Credit Suisse and the Center for Communications Research, La Jolla.</div>
