Meromorphic Convexity on Complex Manifolds

Abstract

The notion of meromorphic convexity is defined and studied on complex manifolds. Using this notion, in analogy with Stein manifolds, a new class of complex manifolds, called {\calligra M }-manifolds, is introduced. This is a class of complex manifolds with a good supply of global meromorphic functions, in particular, it includes all Stein manifolds and projective manifolds. It is also shown that there exist noncompact complex manifolds, known as long ${\mathbb{C}}^2$, that are {\calligra M }-manifolds but do not contain any nonconstant holomorphic functions.
