Analysis of PDEs 2016-11-21 v1

Abstract

The Cauchy problem for the two dimensional compressible Euler equations with data in the Sobolev space Hs(R2)H^s(\mathbb R^2) is known to have a unique solution of the same Sobolev class for a short time, and the data-to-solution map is continuous. We prove that the data-to-solution map on the plane is not uniformly continuous on any bounded subset of Sobolev class functions.
