SUMMARY:Workshop / Seminar:GLNT: Generic character sheaves for parahoric subgroups
DESCRIPTION:Abstract: Lusztig's theory of character sheaves for connected reductive groups is one of the most important developments in representation theory in the last few decades. In this talk\, I will describe a construction which extends this \"depth zero\" picture to give positive-depth character sheaves associated to generic data. In the simplest nontrivial case\, this resolves a conjecture of Lusztig and produces perverse sheaves associated to sufficiently generic multiplicative local systems whose trace-of-Frobenius function coincides with parahoric DeligneLusztig induction. This is joint work with R. Bezrukavnikov.
