DESCRIPTION:Speakers: Kevin Lin (University of Chicago)\n\nExtra talk\nThi
 s talk is about the $L^2$ space of unramified automorphic functions for a
  function field and its conjectural spectral decomposition over the space 
 of Arthur parameters. I will discuss joint work with W. Reeves in which su
 ch a decomposition is established for Borel Eisenstein series. In our appr
 oach\, the Arthur filtration is encoded by the theory of coherent singular
  support on the stack of local systems\, and the passage to function theor
 y is mediated by a categorical trace of Frobenius procedure.\n\nhttps://ma
