Presented by: 
Jørgen Andersen Aarhus Universitet
Date: 
Tuesday 11th April 2017 - 10:00 to 11:00
Venue: 
INI Seminar Room 1
Abstract: 
In this talk we will present a Verlinde formula for the quantization of the Higgs bundle moduli spaces and stacks for any simple and simply-connected group. We further present a Verlinde formula for the quantization of parabolic Higgs bundle moduli spaces and stacks. We will explain how all these dimensions fit into a one parameter family of 2D TQFT's, encoded in a one parameter family of Frobenius algebras, which we will construct.​
