It is a routine job to de ne [0;a] f(s)dA s for f simple, f bounded Borel measurable, and then f positive Borel mea-surable as is done in other measure theory textbooks. For arbitrary Borel measurable WebThe function 1E is a measurable function, if and only if E ∈ M (HW). Definition 9.3. Suppose W ⊂ R is Borel (the set W could be all of R), and let BW:= {B ⊂ W : B ∈ B}. Then (W,BW) is a measurable space. A function g : W → R is called a Borel measur-able function, or just Borel function, if it is measurable with respect to BW. Lemma 9.4.
