Abstract:

We introduce a notion of an asymptotically compact (AC) random dynamical system (RDS). We prove that for an AC RDS the $\Omega$-limit set $\Omega _B(\omega )$ of any bounded set $B$ is nonempty, compact, strictly invariant and attracts the set $B$. We establish that the $2$D Navier Stokes Equations (NSEs) in a domain satisfying the Poincaré inequality perturbed by an additive irregular noise generate an AC RDS in the energy space $\mathrm {H}$. As a consequence we deduce existence of an invariant measure for such NSEs. Our study generalizes on the one hand the earlier results by Flandoli-Crauel (1994) and Schmalfuss (1992) obtained in the case of bounded domains and regular noise, and on the other hand the results by Rosa (1998) for the deterministic NSEs.
