We discuss the existence of equilibrium configurations for the Hamiltonian point-vortex model on a closed surface Sigma. The topological properties of Sigma determine the occurrence of three distinct situations, corresponding to S^2, to RP^2 and to Sigma \not=S^2, RP^2. As a by-product, we also obtain new existence results for the singular mean-field equation with exponential nonlinearity.

Abstract

We discuss the existence of equilibrium configurations for the Hamiltonian point-vortex model on a closed surface Sigma. The topological properties of Sigma determine the occurrence of three distinct situations, corresponding to S^2, to RP^2 and to Sigma \not=S^2, RP^2. As a by-product, we also obtain new existence results for the singular mean-field equation with exponential nonlinearity.
