报告简介:
We establish the ergodicity for stochastic 2D Navier-Stokes equations driven by a highly degenerate pure jump Levy noise. The noise could appear in as few as four directions. The case of Gaussian noise was treated in Hairer and Mattingly [Ann. of Math., 164(3):993--1032, 2006]. To obtain the uniqueness of invariant measure, we use Malliavin calculus and anticipating stochastic calculus to establish the equi-continuity of the semigroup, the so-called e-property, and prove some weak irreducibility of the solution process.
