DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IntSemAutFor
 ms/144/">Spectral theory of automorphic forms: infinite co-volume</a>\nby 
 Chris Lutsko (University of Houston) as part of International seminar on a
 utomorphic forms\n\n\nAbstract\nGiven a Lie group $G$ and a discrete subgr
 oup $\\Gamma < G$\, a critical tool used to analyze automorphic forms is t
 o use spectral decomposition (e.g Selberg trace formula). For rank one hyp
 erbolic manifolds the spectrum is either well understood or far beyond rea
 ch (e.g Selberg eigenvalue conjecture). In infinite volume the spectrum be
 comes linked to interesting geometric features of the manifold. In this ta
 lk I will survey some results about the spectrum of infinite co-volume sub
 groups and the connection to geometry and representation theory. This will
  include work with Dubi Kelmer and Alex Kontorovich\, as well as work with
  Tobias Weich and Lasse Wolf.\n
