Complex Variables 2016-01-06 v1

Abstract

We prove that for any given upper semicontinuous function φ\varphi on an open subset EE of Cn{0}\mathbb C^n\setminus\{0\}, such that the complex cone generated by EE minus the origin is connected, the homogeneous Siciak-Zaharyuta function with the weight φ\varphi on EE, can be represented as an envelope of a disc functional.
