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.
