Abstract: Let $ M$ be an open subset of a Stein manifold without isolated points. Let $ {\Omega ^p}$ be the sheaf of germs of holomorphic $ p$-forms on $ M$. Then $ {H^q}(M,{\Omega ^p})$ is either 0 or else infinite dimensional. $ {H^q}(M,\mathcal{S})$ may be nonzero and finite dimensional if $ M$ is the regular points of a Stein space or if $ \mathcal{S}$ is an arbitrary coherent sheaf over $ M$.
