Abstract.
In this talk I will review some work with Hausel and Rodriguez-Villegas on the computation of the Poincaré polynomial of character varieties (moduli space of representations of fundamental group of punctured Riemann surfaces into GL(n,C)) using arithmetic geometry and the character table of GL(n) over finite fields.
