Let $\struct {X, \Sigma}$ be a measurable space.
Let $\mu : \Sigma \to \C$ be a function.
We say that $\mu$ is a complex measure on $\struct {X, \Sigma}$ if and only if:
\((1)\) | $:$ | \(\ds \map \mu \O \) | \(\ds = \) | \(\ds 0 \) | |||||
\((2)\) | $:$ | \(\ds \forall \sequence {S_n}_{n \mathop \in \N} \subseteq \Sigma: \forall i, j \in \N: S_i \cap S_j = \O:\) | \(\ds \map \mu {\bigcup_{n \mathop = 1}^\infty S_n} \) | \(\ds = \) | \(\ds \sum_{n \mathop = 1}^\infty \map \mu {S_n} \) | that is, $\mu$ is a countably additive function |
