A series of conjectures of Braverman-Kazhdan, Sakellaridis and Sakellaridis-Venkatesh propose that affine spherical varieties should provide a source for new integral representations of automorphic L-functions. This global problem is conjecturally (and sometimes provably) related to a certain local problem in harmonic analysis. In particular, it is conjectured that unramified local L-factors are related to intersection complexes of formal arc spaces of spherical varietes. I will explain how we establish this connection for a large class of spherical varieties over a local function field, using techniques from geometric representation theory. This is joint work with Yiannis Sakellaridis.
