Supports of Weighted Equilibrium Measures and Examples

Abstract

We analyze the supports of weighted equilibrium measures in ${\mathbb{C}}^n$. We give explicit examples of families of compact sets which arise as the support of a weighted equilibrium measure for some admissible weight $w$. These examples also give new constructions of plurisubharmonic functions in the Lelong class. We also include a list of open problems on the support of extremal measures which are related to solutions of Monge-{A}mpère equations.
