Abstract

We discuss some results concerning local hyperconvexity and local hyperconcavity. In the convex case we show that a relatively compact locally hyperconvex open subset D of a complex space X is Stein if there exists a continuous strongly plurisubharmonic function in a neighbourhood of \(\overline D \). In the concave case we study the complement of a complete locally pluripolar set A ⊂ X. If X is Stein we show that A is complete globally pluripolar. A similar result is given for q-complete X. In this case A = ψ = − ∞ with ψ smooth and strongly q-convex outside A. As an application we study the neighbourhoods of complete locally pluripolar sets.
