Distributional comparison for non-commutative infinitely divisible probability measures

Probability 2026-06-29 v1

Abstract

We determine ``cumulant-type'' upper bounds of the non-commutative Wasserstein distance for certain classes of distributions μ\mu and ν\nu, which are infinite divisible with respect to the Boolean, classical and free convolutions. The main contribution of the manuscript is an estimation of the non-commutative Wasserstein distance between μ\mu and ν\nu, expressed in terms of the difference between cumulants of order less than 2m+42m+4.
