报告摘要
This talk addresses the probabilistic well-posedness for the nonlinear Schr\"odinger equation on the two-dimensional sphere. The initial data are distributed according to Gaussian measures with positive regularity in Sobolev spaces . The level of regularity goes beyond existing deterministic results, in a regime where the flow map cannot be extended uniformly continuously. In this talk, I will present the resolution ansatz as well as main steps of the proof. This is a joint work with Nicolas Burq, Nicolas Camps and Nikolay Tzvetkov.
