Title：Large values of eigenfunctions on hyperbolic manifolds
Abstract： It is a folklore conjecture that the sup norm of a Laplace eigenfunction on a hyperbolic surface grows more slowly than any positive power of the eigenvalue. In dimensions three and higher, this was shown to be false by Iwaniec-Sarnak and Donnelly. I will present joint work with Farrell Brumley that strengthens these results, and extends them to locally symmetric spaces associated to SO(p,q).
