A special class of stationary flows for two-dimensional Euler equations: A statistical mechanics description
We consider the canonical Gibbs measure associated to an \(N\)-vortex system in a bounded domain \(\Lambda\), at inverse temperature \(\tilde\beta\) and prove that, in the limit \(N\to\infty\), \(\tilde\beta/N\to\beta\), \(\alpha N\to1\), where \(\beta\in(-8\pi,+\infty)\) (here \(\alpha\) denotes the vorticity intensity of each vortex), the one particle distribution function \(\rho^ N=\rho^ N(x)\), \(x\in\Lambda\) converges to a superposition of solutions \(\rho_ \beta\) of the mean field equation. Finally, we discuss a possible connection of the present analysis with the \(2-D\) turbulence.
