A dual formula for the noncommutative transport distance (2104.11923v2)
Published 24 Apr 2021 in math-ph, math.MP, math.OA, and math.OC
Abstract: In this article we study the noncommutative transport distance introduced by Carlen and Maas and its entropic regularization defined by Becker and Li. We prove a duality formula that can be understood as a quantum version of the dual Benamou-Brenier formulation of the Wasserstein distance in terms of subsolutions of Hamilton-Jacobi-BeLLMann equation.
