摘要：In this talk, we establish the ergodic and mixing properties of stochas tic 2D Navier-Stokes equationsdriven by a highly degenerate multiplicative Gaussian noise. The noise can appear in as few as four directionsand its intensity depends on the solution, The case of additive Gaussian noise was previously treated by Hairerand Mattingly Ann. of Math., 164(3):993-1032, 2006l. To derive the ergodic and mixing properties in the presentsetting, we employ valliavin calculus to establish the asvmptotically strong feller prop erty, the primary challengclies in proving the " invertibility" of the Malliavin matrix, which differs fundamentally from the additive case.
