Mean field equations and domains of first kind

Abstract

In this paper, we are interested in understanding the structure of domains of first and second kind, a concept motivated by problems in statistical mechanics and mean field equations. We prove some openness property for domains of first kind with respect to a suitable topology, as well as some sufficient condition, in terms of the Fourier coefficients of the Riemann map, for a simply connected domain to be of first kind. Finally, we show that the set of simply connected domains of first kind is contractible.
