Point vortex approximation for 2D Navier--Stokes equations driven by space-time white noise

Abstract: We show that the system of point vortices, perturbed by a certain transport type noise, converges weakly to the vorticity form of 2D Navier-Stokes equations driven by the spacetime white noise.

“…This theory was recently revised by means of an alternative approach based on point vortex approximation [33]. These works, devoted to the deterministic equation (1.2) with random initial conditions, have been generalized to stochastic cases, on one hand to the case of multipicative transport noise, see in particular [36,34,38]; on the other hand to the case of additive spacetime white noise and friction [45] (multiplicative noise is formally conservative, while in the case of additive noise a friction is needed to allow stationary solutions). The 2D Euler equations with additive noise, possibly including friction, their corresponding stationary solutions and invariant measures had already been considered before.…”
