Non-Lipshitz flow of the nonlinear Schr\"odinger equation on surfaces

Abstract

We construct non-Lipshitz flow in Hs for the cubic nonlinear Schr\"odinger equation on the 2-torus of revolution with a Lipshitz or smooth metric . The non-Lipshitz property holds for all s<2/3 for Lipshitz metric and s<1/2 for smooth metric. Both coincide with the Sobolev exponents for uniform local well-posedness.
