Regularisation by multiplicative noise for reaction-diffusion equations

Probability 2024-09-18 v1 Analysis of PDEs

Abstract

We consider the stochastic reaction-diffusion equation in 1+11+1 dimensions driven by multiplicative space-time white noise, with a distributional drift belonging to a Besov-H\"older space with any regularity index larger than 1-1. We assume that the diffusion coefficient is a regular function which is bounded away from zero. By using a combination of stochastic sewing techniques and Malliavin calculus, we show that the equation admits a unique solution.
