Berry-Esseen's bound and harmonic moments for supercritical multi-type branching processes in random environments
Résumé
Consider a supercritical multi-type branching process in an independent and identically distributed random environment. We establish a Berry-Esseen type bound for the rate of convergence in the central limit theorem on the population size at time n as n goes to infinity. To this end we first find simple conditions for the existence of harmonic moments of the limit variable of the fundamental martingale.
