Remarks on the Well-Posedness of the Nonlinear Cauchy Problem

Analysis of PDEs 2007-05-23 v1

Abstract

We show that hyperbolicity is a necessary condition for the well posedness of the noncharacteristic Cauchy problem for nonlinear partial differential equations. We give conditions on the initial data which are necessary for the existence of solutions and we analyze Hadamard's instabilities in Sobolev spaces. We also show that genuinely nonlinear equations raise new interesting problems.
