Abstract:
The motion of a finite number of point vortices
on a two-dimensional periodic domain is considered.
In the deterministic case
it is known to be well posed only for almost every
initial configurations. Coalescence of vortices may occur for certain
initial conditions. We prove that when a generic stochastic
perturbation compatible with the Eulerian description is introduced,
the point
vortex motion becomes well posed for
every initial configuration, in particular coalescence disappears.
