String-Math Seminar: Betti Geometric Langlands

Seminar | October 16 | 2-3 p.m. | 402 LeConte Hall

 David Nadler, UC Berkeley

 Department of Mathematics

I’ll describe a variant of the geometric Langlands program that has more of the topological flavor of some physical accounts. I’ll explain how it fits into broader patterns in mirror symmetry, and also the form it takes in some examples. A key quest is for a “categorical Verlinde formula” to reduce the case of high genus curves to nodal configurations. (Joint work in parts with D. Ben-Zvi and Z. Yun.)
