Abstract

We use radial estimates for pseudodifferential operators to describe long-time evolution of solutions to iutPu=f, where P is a self-adjoint zeroth-order pseudodifferential operator satisfying hyperbolic dynamical assumptions and where f is smooth. This is motivated by recent results of Colin de Verdière and Saint-Raymond (2019) concerning a microlocal model of internal waves in stratified fluids.
