Integration, chapter V, § 3. Integration of positive measures

— Let μ\mu be a positive measure on TT that belongs to the domain of Λ\Lambda, and let ff be a universally measurable function ≥0\geq 0 defined on XX. If ff is moderated for the measure μΛ\mu \Lambda, or if the measures λt\lambda_t are bounded, then the function Λf\Lambda f is μ\mu-measurable and

⟨μΛ,f⟩=⟨μ,Λf⟩. \langle \mu \Lambda, f \rangle = \langle \mu, \Lambda f \rangle .

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
