RT Book, Section T1 Representation Variety for the Rank One Affine Group A1 González Prieto, José Ángel A1 Logares Jiménez, Marina Lucía A1 Muñoz Velázquez, Vicente AB The aim of this chapter is to study the virtual classes of representation varieties of surface groups onto the rank one affine group. We perform this calculation by three different approaches: the geometric method, based on stratifying the representation variety into simpler pieces; the arithmetic method, focused on counting their number of points over finite fields; and the quantum method, which performs the computation by means of a Topological Quantum Field Theory. We also discuss the corresponding moduli spaces of representations and character varieties, which turn out to be non-equivalent due to the non-reductiveness of the underlying group.
