I’m speaking at the AGNES workshop on the last weekend in April, at Stony Brook (click here for more workshop information).
Title: The Chow ring of a finite group
Abstract: A natural class of singular varieties consists of the quotients of vector spaces by linear actions of a finite group G. We can ask what the Chow group of algebraic cycles is, for such a quotient. By taking larger and larger representations of G, we can package these Chow groups into a ring, called the Chow ring of the classifying space of G, or (for short) the Chow ring of G. It maps to the cohomology ring of G, usually not by an isomorphism.
We present the latest tools for computing Chow rings of finite groups. These tools give complete calculations for all “small” groups and many other finite groups. A surprising point is that Chow rings become “wild,” in a precise sense, for some slightly larger finite groups.
The Spring 2014 workshop of AGNES (Algebraic Geometry Northeastern Series) is the weekend of Friday-Sunday, April 25-27, in the Simons Center at Stony Brook University. There are funds to support participants. The registration deadline is March 15th.
The list of confirmed and tentative speakers is as follows.
Ron Donagi (Pennsylvania)
Eugene Gorsky (Columbia)
Sandor Kovacs (Washington)
James McKernan (UC San Diego)
Zsolt Patakfalvi (Princeton)
Michael Thaddeus (Columbia)
Burt Totaro (UCLA)
Cynthia Vinzant (Michigan)
The webpage for the workshop is at the following URL.
There is a registration form on the webpage. The deadline is March 15th, but particularly for funding purposes, participants are encouraged to register as soon as possible.
Additional details will be announced on the workshop webpage. We hope to see you at AGNES Spring 2014.
Organizers: Samuel Grushevsky, Radu Laza, Robert Lazarsfeld, Jason Starr
