The standard change of variable formula, for T measurable from a measure space (S,S,λ) to a measurable space (S¯,S¯) on which a measurable t¯ is defined (see e.g.[H]), St¯Tdλ=S¯t¯d(λT1), is developed for a semigroup valued refinement integral. (The integral on the right can be rewritten in “Jacobian” form, S¯t¯dλT1dλ¯dλ¯, when λT1 is differentiable with respect to a measure λ¯ on S¯; the attempt in [DS] Lemma III.10.8 to develop the result by starting from λ¯ is incorrect). This yields a result for the order-convergent integral of real-valued integrands against positive finitely additive measures in an Archimedian ordered vector space as well as a (correct) result for the [DS] Banach space valued integral of a vector valued integrand against a real-valued finitely additive measure.
