Definition

Let $U \subset \C$ be an open subset of the complex plane $\C$.


A meromorphic function on $U$ is a complex function that can be expressed as the ratio of two holomorphic functions.

That is:

$\map f z = \dfrac {\map g z} {\map h z}$

where:

$g: \C \to \C$ and $h: \C \to \C$ are holomorphic
$z \in \C$ such that $\map h z \ne 0$
