These talks should be aimed at beginning graduate students, and could try to explain some of the background, terminology, and ideas for the grown-up AG talk that week, or can be about whatever you have been thinking about recently.

Abstract: The Cartier duality is an algebraic version of the Pontryagin duality. A finite commutative group may be viewed either as a locally compact group or as a discrete algebraic group. Accordingly,  its dual can be interpreted in the topological way (the Pontryagin dual: the group of continuous characters to U(1)) or in the algebraic way (the Cartier dual: the group of regular characters to the multiplicative group). The Cartier duality extends to a beautiful and non-trivial correspondence on a wider class of affine commutative algebraic groups; this is similar to the extension of the Pontryagin duality from finite groups to locally compact groups.

Abstract: This is a continuation of my talk last week. The goal is to extend the Cartier duality to infinite commutative algebraic groups (and group ind-schemes). I will consider several examples, concluding with the one that is perhaps most spectacular: the Contou-Carrere symbol (the algebro-geometric version of the Hilbert symbol).

Revision as of 21:10, 29 January 2014

Wednesdays 4pm, Room - Van Vleck B219

The purpose of this seminar is to have a talk on each week by a graduate student to help orient ourselves for the Algebraic Geometry Seminar talk on the following Friday. These talks should be aimed at beginning graduate students, and could try to explain some of the background, terminology, and ideas for the grown-up AG talk that week, or can be about whatever you have been thinking about recently.

Give a talk!

We need volunteers to give talks this semester. If you're interested contact Nathan. Beginning graduate students are particularly encouraged to give a talk, since it's a great way to get your feet wet with the material.
