Probabilistic well-posedness for the nonlinear wave equation on $B_2\times \mathbb{T}$

Abstract

We establish probabilistic well-posedness results for the subcubic nonlinear wave equation, posed on the domain $B_2\times \mathbb{T}$, with randomly chosen initial data having radial symmetry in the $B_2$ variable, and with vanishing Dirichlet boundary conditions on $\partial B_2\times \mathbb{T}$.
