Large Deviations Principle for 2D Navier–Stokes Equations with Space-time Localized Noise

Communications in Mathematics and Statistics ›› : 1 -17.
We consider a stochastic 2D Navier–Stokes equation in a bounded domain. The random force is assumed to be non-degenerate and periodic in time; its law has a support localized with respect to both time and space. Slightly strengthening the conditions in the pioneering work about exponential ergodicity by Shirikyan [21], we prove that the stochastic system satisfies Donsker–Varadhan-type large deviations principle. Our proof is based on a criterion of [10] in which we need to verify uniform irreducibility and uniform Feller property for the related Feynman–Kac semigroup.
