Spaces of analytic functions on essentially pluripolar compacta

Abstract

Let $A\left( K\right) $ be the locally convex space of all analytic germs on a compact subset $K$ of a Stein manifold $\Omega $, $\dim \Omega =n$, endowed with the standard inductive topogy, let $0^{n}$ denote the origin of $\mathbb{C}^{n}$, The main result is the characterisation of the isomorphism $A\left( K\right) \simeq A\left( \left\{ 0^{n}\right\} \right) $ in terms of pluripotential theory. It is based on the general result of Aytuna-Krone-Terzio\u{g}lu on the characterisation of power series spaces of infinite type in terms of interpolational invariants $\left( DN\right) $ and $\left( \Omega \right)$.
