Cartan theorem A (Theorem)

Let $\mathcal{O}_z$ denote the ring of germs of holomorphic functions at $z$

Theorem 1 (Cartan)   Suppose $\mathcal{F}$ is a coherent analytic sheaf on a Stein manifold $M$ . For every $z \in M$ , the the stalk ${\mathcal{F}}_z$ is generated as an ${\mathcal{O}}_z$ module by the germs at $z$ of the sections $\Gamma(M,\mathcal{F})$ .

Philosophically, this theorem says that there is good supply of global sections of a coherent analytic sheaf on a Stein manifold.
