The Kato smoothing effect for the nonlinear regularized Schrödinger equation on compact manifolds

Abstract

<p style='text-indent:20px;'>We establish Strichartz estimates for the regularized Schrödinger equation on a two dimensional compact Riemannian manifold without boundary. As a consequence we deduce global existence and uniqueness results for the Cauchy problem for the nonlinear regularized Schrödinger equation and we prove under the geometric control condition the Kato smoothing effect for solutions of this equation in this particular geometries.
