Revision as of 13:37, 17 September 2015
When: Wednesdays 4:00pm
Where:Van Vleck B325
Who: YOU!!
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.
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 here.
Give a talk!
We need volunteers to give talks this semester. If you're interested contact 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.
Wish List
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.
- Bondal and Orlov: semiorthogonal decompositions for algebraic varieties (Note: this is about cool stuff like Fourier-Mukai transforms)
- 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)
- homological projective duality
- moment map and symplectic reduction
- the orbit method (for classifying representations of a Lie group)
- Kaledin: geometry and topology of symplectic resolutions
- Kashiwara: D-modules and representation theory of Lie groups (Note: Check out that diagram on page 2!)
- geometric complexity theory, maybe something like arXiv:1508.05788.

Title: A^1 homotopy theory and rank-2 vector bundles on smooth affine surfaces |
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. |

Title: Moduli Spaces of Sheaves on Singular Curves |
Abstract: I will explain some useful techniques for the study of sheaves on singular curves. In particular, there are many isomorphisms between moduli spaces of different sorts of sheaves on a given curve coming from natural operations on sheaves. |
