Global well-posedness for the mass-critical stochastic nonlinear Schr\"{o}dinger equation on $\mathbb{R}$: small initial data

Abstract

We prove the global existence of solution to the small data mass critical stochastic nonlinear Schr\"{o}dinger equation in $d=1$. We further show the stability of the solution under perturbation of initial data. Our construction starts with the existence of the solution to the truncated subcritical problem. We then obtain uniform bounds on these solutions that enable us to reach criticality and then remove the truncation.
