Generalizations of the fourth moment theorem

N. Naganuma

Abstract:

Azmoodeh {et al.} established a criterion regarding convergence of the and even moments of random variables in a Wiener chaos with fixed order guaranteeing the central convergence of the random variables. This was a major step in studies of the fourth moment theorem. In this paper, we provide further generalizations of the fourth moment theorem by building on their ideas. More precisely, further criteria implying central convergence are provided: (i) the convergence of the and even moment, (ii) the convergence of the and even moments.
