Stein manifold

Summary

A Stein manifold is a complex manifold with enough global holomorphic functions: they separate points and give compact holomorphically convex hulls of compact sets. Stein manifolds are the complex analogue of affine varieties, and they are exactly the closed complex submanifolds of some ℂN\C^N. On them the main problems of several complex variables, such as the Cousin problems, are governed by topology, through Cartan's theorems A and B.
