Abstract
We study the growth rate of Lp norms of eigenfunctions of the Laplace-Beltrami operator restricted to submanifolds of compact C ∞ Riemannian manifolds. The spectral projection operators can be expressed as oscillatory integral operators, so the question reduces to oscillatory integral operator norm estimates. We study the relationship between the extrinsic geometry of these submanifolds and the canonical relations associated to these oscillatory integral operators.
