Gibbs Equilibrium Fluctuations of Point Vortex Dynamics
Francesco Grotto, Eliseo Luongo, Marco Romito
We consider a system of N point vortices in a bounded domain with null total circulation, whose statistics are given by the Canonical Gibbs Ensemble at inverse temperature $β\geq 0…

Zero-Noise Selection for Point Vortex Dynamics after Collapse
Francesco Grotto, Marco Romito, Milo Viviani
The continuation of point vortex dynamics after a vortex collapse is investigated by means of a regularization procedure consisting in introducing a small stochastic diffusive term…
