Higher order Ito product formula and generators of evolutions and flows. (English) Zbl 0850.81035

Summary: A simple combinatorial formula is found for the product of two iterated quantum stochastic integrals, and used to find conditions that such an integral represent a unitary-valued or \(*\)-algebra homomorphism-valued process.
