Content:

A measurable function $f : \Omega \to \reals$ where $(\Omega, \mathcal{A}, \mu)$ is a measure space is said to be {\bf summable} or {\bf integrable} if the Lebesgue integral of the absolute value of $f$ exists and is finite,
\begin{equation*}
\int_{\Omega} |f| d\mu < +\infty
\end{equation*}
