Point Source Equilibrium Problems with Connections to Weighted Quadrature Domains

Abstract

We explore the connection between supports of equilibrium measures and quadrature identities, especially in the case of point sources added to the external field $Q(z)=|z{|}^{2p}$ with $p\in \mathbb{N}$. Along the way, we describe some quadrature domains with respect to weighted area measure $|z{|}^{2p}d{A}_z$ and complex boundary measure $|z{|}^{-2p}dz$.
