Gradient NLW on curved background in 4+1 dimensions

Analysis of PDEs 2008-02-27 v1

Abstract

We obtain a sharp local well-posedness result for the Gradient Nonlinear Wave Equation on a nonsmooth curved background. In the process we introduce variable coefficient versions of Bourgain's Xs,bX^{s,b} spaces, and use a trilinear multiscale wave packet decomposition in order to prove a key trilinear estimate.
