Product Formula, Independence and Asymptotic Moment-Independence for Complex Multiple Wiener-Ito Integrals

We present the product formula for complex multiple Wiener-Ito integrals. As applications, we show the Ustunel-Zakai independent criterion, the Nourdin-Rosinski asymptotic moment-independent criterion and joint convergence criterion for complex multiple Wiener-Ito integrals.
