Student Representation Theory Seminar

Winter 2015

In Winter 2015, we meet on Tuesdays and Thursdays at 3pm in the Barn (Ry 352). On Thursdays, we are reading through the notes Homogeneous Spaces and Equivariant Embeddings (arXiv) by D. A Timashev. On Tuesdays, we discuss the class Geometric Satake and Hecke Algebras, which is being taught by Victor Ginzburg.

Autumn 2014

The organizers for the seminar are now Ana Balibanu and Sergei Sagatov. We met on Thursdays at 3pm in the Barn (Ry 352). The topic was Character Sheaves.

We loosely followed these references:

The talks were given by Jonathan Wang.
