Almost sure scattering for the energy-critical NLS with radial data below $H^1(\mathbb{R}^4)$ (1707.09051v1)

Abstract: We prove almost sure global existence and scattering for the energy-critical nonlinear Schr\"odinger equation with randomized spherically symmetric initial data in $H^s(\mathbb{R}^4)$ with $\frac56<s<1$. We were inspired to consider this problem by the recent work of Dodson--L\"uhrmann--Mendelson, which treated the analogous problem for the energy-critical wave equation.
