Regularized vortex approximation for 2D Euler equations with transport noise

Probability 2020-09-25 v2

Abstract

We study a mean field approximation for the 2D Euler vorticity equation driven by a transport noise. We prove that the Euler equations can be approximated by interacting point vortices driven by a regularized Biot-Savart kernel and the same common noise. The approximation happens by sending the number of particles NN to infinity and the regularization ϵ\epsilon in the Biot-Savart kernel to 00, as a suitable function of NN.
