it is a folklore conjecture that the sup norm of a laplace eigenfunction on a compact 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 $\mathrm{so}(p,q)$.
