Title: Open sets satisfying an intermediate vanishing condition of cohomology groups
Abstract:
In this talk, we consider open sets satisfying an intermediate vanishing condition of cohomology groups. We show that the boundaries of those open sets satisfy an intermediate continuity principle and give a new proof of a result of Eastwood-Suria (1980). As an application, we obtain a theorem of Serre (1953) that a vanishing condition of the cohomology group with respect to the structure sheaf is equivalent to the Steinness in complex Euclidean space.
