Gluing semiclassical resolvent estimates via propagation of singularities (1008.3964v2)
Published 24 Aug 2010 in math.AP
Abstract: We use semiclassical propagation of singularities to give a general method for gluing together resolvent estimates. As an application we prove estimates for the analytic continuation of the resolvent of a Schr\"odinger operator for certain asymptotically hyperbolic manifolds in the presence of trapping which is sufficiently mild in one of several senses. As a corollary we obtain local exponential decay for the wave propagator and local smoothing for the Schr\"odinger propagator.
