Abstract: We consider the extremal plurisubharmonic functions $ L_E^\ast $ and $ U_E^\ast $ associated to a nonpluripolar compact subset $ E$ of the unit ball $ B \subset {{\mathbf{C}}^n}$ and show that the corresponding Monge-Ampère measures $ {(d{d^c}L_E^\ast )^n}$ and $ {(d{d^c}U_E^\ast )^n}$ are mutually absolutely continuous. We then discuss the polynomial growth condition $ ({L^\ast})$, a generalization of Leja's polynomial condition in the plane, and study the relationship between the asymptotic behavior of the orthogonal polynomials associated to a measure on $ E$ and the $ ({L^\ast})$ condition.
