Deligne-Lusztig Seminar (Lent 2022)

This study group is loosely organized around further developments in Deligne-Lusztig theory. The goal is to gain some broad exposure to the circle of ideas in the subject without focusing too heavily on any particular proof.

We meet on Thursdays at 2:30 pm in MR11. Anyone is welcome to participate!
