"WebThe ﬁrst part of this theorem is known as the 4th moment theorem, proved originally by Nualart and Peccati in Nualart and Peccati (2005). The second part, i.e. relation (1.1), suggests that the third moment is just as important as the 4th moment when investigating the normal convergence of sequences in a ﬁxed Wiener chaos.
