On the Levi problem with singularities

Abstract

In section 1, we show that if $X$ is a Stein normal complex space of dimension n and $D\subset \subset X$ an open subset which is the union of an increasing sequence $D_1\subset D_2\subset ...\subset D_n\subset >...$ of domains of holomorphy in $X$. Then $D$ is a domain of holomorphy. In section 2, we prove that a domain of holomorphy $D$ which is relatively compact in a 2-dimensional normal Stein space $X$ itself is Stein. In section 3, we show that if $X$ is a Stein space of dimension n and $D\subset X$ an open subspace which is the union of an increasing sequence $D_1\subset D_2\subset ...\subset D_n\subset ...$ of open Stein subsets of $X$. then $D$ itself is Stein, if $X$ has isolated singularities.
