Title: L^p Bounds for Eigenfunctions on Locally Symmetric Spaces

Abstract: there is a classical theorem of Sogge which provides 
bounds for the L^p norms of a Laplace eigenfunction on a compact 
Riemannian manifold, which are sharp on the sphere and for spectral 
clusters. I will present a generalization of this theorem to 
eigenfunctions of the full ring of invariant differential 
operators on a locally symmetric space, as well as a theorem on 
the restriction of eigenfunctions to maximal flat subspaces. 
Time permitting, I will discuss ways in which these bounds can 
be improved using inputs from number theory.
