We consider a stochastic version of the point vortex system, in which the
fluid velocity advects single vortices intermittently for small random times.
Such system converges to the deterministic point vortex dynamics as the rate at
which single components of the vector field are randomly switched diverges, and
therefore it provides an alternative discretization of 2D Euler equations. The
random vortex system we introduce preserves microcanonical statistical
ensembles of the point vortex system, hence constituting a simpler alternative
to the latter in the statistical mechanics approach to 2D turbulence.Comment: 9 pages, 0 figure
