We prove that a complex surface that contains an infinite Nori string of rational curves is not $$p_5$$ -convex and that a covering of a 1-convex complex surface which does not contain an infinite Nori string of rational curves is $$p_5$$ -convex.

We consider a more general form of the Levi problem for Stein spaces, namely the Levi problem for unbranched Riemann domains spread over Stein spaces. We raise four problems related to this...

We discuss some open problems in the theory of analytic pseudoconvexity. We focus our attention especially on q-complete spaces and Stein spaces.

We prove that every reduced, second countable, connected complex space X can be written as a finite union of connected Stein open subsets. If X is irreducible, we show that these Stein open subsets can be chosen to be contractible. We also prove that

We construct a 1-convex surface X such that its universal covering X ˜ has the property that H 1 ( X ˜ , O X ˜ ) is not separated.

We consider a germ of a two-dimensional complex singularity \((X,x_0)\), irreducible at \(x_0\) and \(F\) the exceptional divisor of a desingularization. We prove that if there exists a normal isolated singularity \((Z,z_0)\) with simply connected li

We give two examples of complex spaces on which global holomorphic functions separate points and give local coordinates and they cannot be realized as open subsets of Stein spaces. At the same time we notice that these examples are open subsets of St

We construct an example of a 2-dimensional Stein normal space X with one singular point x 0 such that X\{x 0} is simply connected and it satisfies the disk condition. This answers a question raised by Fornaess and Narasimhan. We also prove that any i
