Meromorphic 2002-01-04 01:37:47 2008-10-25 15:45:56 Definition \usepackage{amssymb} \usepackage{amsmath} \usepackage{amsfonts} \usepackage{graphicx} \usepackage{xypic} Let $U \subset \mathbb{C}$ be a domain. A function $f\colon U \to \mathbb{C}$ is \emph{meromorphic} if $f$ is holomorphic except at an isolated set of poles. It can be proven that if $f$ is meromorphic then its set of poles does not have an accumulation point.
