# CCA Reading Group

This is the page for the Fall 2019 Computational Commutative Algebra Reading Group, which is open to all UW Math grad students, but will require a certain amount of participation and work to receive credit.

## Resources

We plan to read Cox, Little, and O'Shea's *Ideals, Varieties, and Algorithms*, which can be found here: [1].

## Meeting Schedule

10 weeks total, starting on Sept. 16, adjusting throughout the semester.

Meetings will be on Mondays at 3:30-5:30pm, split into two sessions, in B129 VV.

We will also have additional problem sessions (optional) on Thursdays at 2:30-3:30pm in B119 VV, and on Fridays at 10-11am in B321 VV.

Exact schedule may vary slightly from week to week as needed.

## General Meeting Structure

This reading group will be structured as follows. Every meeting will have an assigned speaker, who will usually be one of the reading group participants, but could at times be an older grad student or professor. It will be expected that everyone attending will read the assigned sections prior to the meeting. The speaker is expected to additionally work out some examples prior and will be responsible for lecturing on the reading material and guiding the group discussion during the meeting. The schedule will be pretty flexible and will be adjusted throughout the semester. Daniel Erman will be our faculty advisor, and in order to receive credit (up to 3 credits), participants will be expected to attend all meetings, be the speaker twice, and do several exercises. We will also use Macaulay2 during the exercise sessions to get comfortable both computing examples by hand and by using a computer.
