Title: Arithmetic Geometry of Moduli of Representations

ABSTRACT: Let Γ be a finitely generated group and G a connected reductive group. The moduli space of representations of Γ into G, also known as the character variety (or character stack), plays a central role in diverse areas of mathematics, including Geometric Langlands and non-abelian Hodge Theory. In this talk, I will explain how one goes about counting points on the moduli space over finite fields. As we shall see, salient features of complex representations theory of finite reductive groups (Deligne—Lusztig theory, etc.) comes into play.
