Escape of mass on Hilbert modular surfaces
Abstract
Quantum Unique Ergodicity has been a widely studied conjecture of Rudnick and Sarnak (1994), concerning the distribution of large frequency eigenstates on a negatively curved manifold. Arithmetic Quantum Unique Ergodicity (AQUE) restricts the problem to arithmetic manifolds, such as SL(2,Z) \ H, the classical modular surface. Work of Lindenstrauss (2006) combined with the elimination of escape of mass proved by Soundararajan (2010) confirmed AQUE for the classical modular surface. This talk is concerned with AQUE for Hilbert modular surfaces, and in particular, my thesis work involving the elimination of escape of mass in this case.
