Abstract

The point of this talk is to show how certain well-posedness results  that are not available using deterministic techniques involving Fourier and harmonic analysis 

can be obtained when introducing randomization in the set of initial data. Along the way I will also prove a certain “probabilistic propagation of regularity” for certain almost sure globally well-posed dispersive equations. This talk is based on joint work with A. Nahmod
