WebA signed measure taking values in [0;1] is what we have dealt with in Chapters 2{7; sometimes we call this a positive measure. If 1 and 2 are positive measures and one of them is nite, then 1 2 is a signed measure. The following result is easy to prove but useful. Proposition 8.1. If is a signed measure on (X;M); then for a sequence fEjg ˆ M; WebA Borel measure is any measure defined on the σ-algebra of Borel sets.
