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. |
