Abstract

Every multiplier algebra of an irreducible complete Pick kernel arises as the restriction algebra MV={f∣∣V:f∈Md} , where d is some integer or ∞,Md is the multiplier algebra of the Drury-Arveson space H2d , and V is a subvariety of the unit ball. For finite dimensional d it is known that, under mild assumptions, every isomorphism between two such algebras MV and MW is induced by a biholomorphism between W and V. In this paper we consider the converse, and obtain positive results in two directions. The first deals with the case where V is the proper image of a finite Riemann surface. The second deals with the case where V is a disjoint union of varieties.
