Title: Mixed Hodge structure of character varieties
Date: Tue, Aug 08, 2017, 13:15 - 14:45
Place: Seminar Room A
Abstract: In this talk I will discuss the conjectures with Hausel and Letellier that describe the mixed Hodge structure of the character varieties parameterizing finite dimensional representations of the fundamental group of a Riemann surface. The formulation of these conjectures involve the Macdonald polynomials and arose from counting points of the varieties over finite fields.
