2D Navier-Stokes equation with cylindrical fractional Brownian noise

Abstract

We consider the Navier-Stokes equation on the 2D torus, with a stochastic forcing term which is a cylindrical fractional Wiener noise of Hurst parameter $H$. Following [3,8] which dealt with the case $1/2$, we prove a local existence and uniqueness result when $7/16<H<1/2$ and a global existence and uniqueness result when $1/2<H<1$.
