Abstract

We prove a quantum ergodic restriction (QER) theorem for real hypersurfaces ΣX,\Sigma \subset X, where XX is the Grauert tube associated with a real-analytic, compact Riemannian manifold. As an application, we obtain hh independent upper and lower bounds for the L2L^2 - restrictions of the FBI transform of Laplace eigenfunctions restricted to Σ\Sigma satisfying certain generic geometric conditions.
