Dispersive type estimates for Fourier integrals and applications to hyperbolic systems

Analysis of PDEs 2012-03-20 v1

Abstract

In this note we provide dispersive estimates for Fourier integrals with parameter-dependent phase functions in terms of geometric quantities of associated families of Fresnel surfaces. The results are based on a multi-dimensional van der Corput lemma due to the first author. Applications to dispersive estimates for hyperbolic systems and scalar higher order hyperbolic equations are also discussed.
