Abstract
Multiple stochastic integrals of Huang and Cambanis [1978. Stochastic and multiple Wiener integrals for Gaussian
processes. Ann. Probab. 6, 585­614] with respect to a general Gaussian process X ¼ ðXt; t 2 TÞ, whose covariance function
is of bounded variation on bounded subsets of T Â T, are considered. A product formula for the integrals is derived and a
necessary and sufficient condition for independence of multiple Huang­Cambanis integrals is obtained. As an illustration,
the results are applied to the special case of multiple integrals with respect to a persistent fractional Brownian motion.

1. Introduction
The problem of finding necessary and sufficient conditions for independence of multiple stochastic integrals
in terms of their deterministic integrands was initially addressed by U¨ stu¨ nel and Zakai (1989) in the context of
