Demailly, Jean-Pierre Cohomology of q-convex spaces in top degrees. (English) Zbl 0682.32017 Math. Z. 204, No. 2, 283-295 (1990). It is shown that every strongly q-complete subvariety of a complex analytic space has a fundamental system of strongly q-complete neighborhoods. As a consequence, we find a simple proof of Ohsawa’s result that every non compact irreducible n-dimensional analytic space is strongly n-convex. An elementary proof of the existence of Hodge decomposition in top degrees for absolutely q-convex manifolds is also given.
