Abstract
We prove that if (M, g) is a compact Riemannian manifold with ergodic geodesic flow, and if H ⊂ M is a smooth hypersurface satisfying a generic microlocal asymmetry condition, then restrictions φj{pipe}H of an orthonormal basis {φj} of Δ-eigenfunctions of (M, g) to H are quantum ergodic on H. The condition on H is satisfied by geodesic circles, closed horocycles and generic closed geodesics on a hyperbolic surface. A key step in the proof is that matrix elements 〈 Fφj, φj〉 of Fourier integral operators F whose canonical relation almost nowhere commutes with the geodesic flow must tend to zero.
