Category:Intersection Signed Measures

This category contains results about intersection signed measures.
Definitions specific to this category can be found in Definitions/Intersection Signed Measures.

Let $\struct {X, \Sigma}$ be a measurable space.

Let $\mu$ be a signed measure on $\struct {X, \Sigma}$.

Let $F \in \Sigma$.

Then the intersection (signed) measure (of $\mu$ by $F$) is the mapping $\mu_F: \Sigma \to \overline \R$, defined by:

$\map {\mu_F} E = \map \mu {E \cap F}$

for each $E \in \Sigma$.
