Montel's theorem (Theorem)

Suppose that $G \subset {\mathbb{C}}$ is a region.

Theorem 1 (Montel)   A set ${\mathcal{F}}$ of holomorphic functions $f\colon G \to {\mathbb{C}}$ is normal if and only if ${\mathcal{F}}$ is locally bounded.

In other words a sequence of holomorphic functions $\{ f_n \}$ has a subsequence which converges uniformly on compact subsets to a holomorphic function $f \colon G \to {\mathbb{C}}$ if and only if the set $\{ f_n \}$ is locally bounded.
