Abstract:
We consider the Navier-Stokes equation on a two dimensional torus with a random force which is white noise in time, and excites only a finite number of modes. The number of excited modes depends on the viscosity ν, and grows like ν -3 when ν goes to zero. We prove that this Markov process has a unique invariant measure and is exponentially mixing in time.
