On the supercritical Schrödinger equation on the exterior of a ball
arXiv:2106.16183
Abstract
We consider the mixed problem on the exterior of the unit ball in , , for a defocusing Schrödinger equation with a power nonlinearity , with zero boundary data. Assuming that the initial data are non radial, sufficiently small perturbations of \emph{large} radial initial data, we prove that for all powers the solution exists for all times, its Sobolev norms do not inflate, and the solution is unique in the energy class.
