Title: Crystalline extensions and the weight part of Serre's conjecture
Speaker: David Savitt
Speaker Info: Arizona and Northwestern
Special Note: There will be an introductory preseminar talk 2:00-2:45 in 101 Annenberg Hall.
We will discuss the proof of the weight part of Serre's conjecture for rank two unitary groups in the totally ramified case. Our methods are a mixture of local and global techniques, and in the course of the proof we establish some purely local results on crystalline extension classes. This is joint work with Toby Gee and Tong Liu.Date: Monday, November 07, 2011
