Abstract

A quantitative “fourth moment theorem” for any self-adjoint element in a homogeneous Wigner chaos is provided: the Wasserstein distance is controlled by the distance from the fourth moment to two. The proof uses the free counterpart of the Stein discrepancy. On the way, the free analogues of the WS inequality and the WSH inequality are established.
