Definition: Measureable Function

Let \((M,{\mathcal {A}})\) und \((N,{\mathcal {B}})\) be two measurable sets. A function \(\varphi \colon M\longrightarrow N\,\) is called measureable (or \({\mathcal {A}}-{\mathcal {B}}\)-measureable), if for all \(T\in {\mathcal {B}}\) the inverse image \(\varphi ^{-1}(T)\) is in \({\mathcal {A}}\).
