Algebra Seminar

The p-smoothness locus of Schubert varieties

Geordie Williamson

8th August, 12:05-12:55pm, Carslaw 159


Abstract

An n-dimensional complex variety is p-smooth if local cohomology with characteristic p coefficients cannot distinguish it from Cn. I will begin by discussing this notion on some examples and then describe joint work with Peter Fiebig determining the p-smooth locus of Schubert varieties for many primes p. If time permits, I will also try to sketch why such questions are important in modular representation theory (this is work due to Soergel, Mirkovic-Vilonen, Fiebig and Juteau).


After the seminar we will take the speaker to lunch.

See the Algebra Seminar web page for information about other seminars in the series.
