Representations of Fuchsian groups and torsors under Bruhat-Tits group schemes, Part II
Let π be a Fuchsian group acting on the upper half plane with elliptic fixed points. Let G be a semisimple simply connected algebraic group and KG be a maximal compact subgroup of G. In this talk I will show that the space of (irreducible) representations of π→KG (with fixed conjugacy classes of the finite order elements) modulo conjugacy can be given a modular description in terms of (stable) polystable torsors of a canonically defined Bruhat-Tits group scheme associated to a parahoric datum coming from the datum of the conjugacy classes. I will indicate several developments which have arisen from this perspective.
