SUMMARY:Special functions and building Kuznetsov formulas on GL(n)
LOCATION:HLL 525
DESCRIPTION:Abstract:\nMany of the constructions of analytic number theory generalize f
 rom the classical GL(2) objects (like modular/Maass forms, Kloosterman sums
 , and L-functions) to GL(n), and studying these new objects involves specia
 l functions on GL(n) (like Bessel functions, zonal spherical functions, and
  Whittaker functions).  I'll discuss several of these new functions and the
 ir roles in constructing Kuznetsov-type trace formulas.\nThe past few years
 , I've been on a quest to find integral representations for the Bessel func
 tions occurring in the GL(n) Kuznetsov formula.  We have these for GL(2), G
 L(3) and now GL(4) and I think I know how to construct them for GL(n).  I'l
 l discuss the spectral families on GL(n) and their corresponding Kuznetsov 
 formulas.  Finally, I'll talk about the integral representations we want fo
 r the Bessel functions and how (I hope) they lead to applications like Weyl
  laws, moments and subconvexity of L-functions.\n
