DESCRIPTION:Speaker: Jonathan Wang\nhosted by Tamas Hausel\nAbstract: The r
 elative Langlands program\, as developed by Sakellaridis and Venkatesh\, c
 onjectures relationships between spherical varieties and automorphic L-fun
 ctions. In the local setting\, this is conjecturally related to the comput
 ation of asymptotics\, or more precisely nearby cycles\, of an IC complex 
 on the formal arc space of a spherical variety. I explain my joint work wi
 th Yiannis Sakellaridis where we establish this connection and compute thi
 s nearby cycles for a nice class of spherical varieties using perverse she
 aves and the geometry of semi-infinite orbits and affine Grassmannians.
