# Kazhdan seminar: Tomer Schank "Sheaves with nilpotent support"

Repeats every week every Sunday until Sun Jan 17 2021 .

2:00pm to 4:00pmAbstract: Given a smooth and proper curve X and a reductive group G one can consider the stack Bun_{G,X} of principal G-bundles on X. This stack has an important role in Algebraic Geometry and Representation Theory especially with regard to the Langlands program. We shall study the geometry of Bun_{G,X} and the category

D(G,X) of constructible sheaves on Bun_{G,X}. We shall be especially interested in the subcategory D_{nil}(G,X) of sheaves with nilpotent singular support.
