Riemann domains over Stein spaces
Rigidity of Holomorphic Self-Mappings and the Automorphism Groups of Hyperbolic Stein Spaces.
Runge families and inductive limits of Stein spaces
The general Stein union problem is solved: given an increasing sequence of Stein open sets, it is shown that the union is Stein if and only if is Hausdorff separated.
Rungescher Satz and a condition for Steiness for the limit of an increasing sequence of Stein spaces
A necessary and sufficient condition, which is a weak converse of a classical theorem of Behnke-Stein, in order that a limit of Stein spaces be again a Stein space is proved.
