Summary

LetX=(X 1, ...,X d ) be an ℝd Lévy process on ℝ+ or ergodic exchangeable process on [0, 1], and letV=(V 1, ...,V d ) be a predictable process on the same interval. Under suitable moment conditions, it is shown that, if the Lebesgue integrals\(\int {\prod\limits_{j \in J} {V_j } } \) are a.s. non-random for allJ⊂{1, ...,d} with #J≦d-1 or #J≦d, respectively, then the product moment EΠ∫V j dX j is the same as ifX andV were independent. An analogous statement holds in discrete time. The results imply some invariance properties of exchangeable sequences and processes under suitable predictable transformations
