Characterization of optimal Transport Plans for the Monge-Kantorovich-Problem

Abstract

We prove that cc-cyclically monotone transport plans π\pi optimize the Monge-Kantorovich transportation problem under an additional measurability condition. This measurability condition is always satisfied for finitely valued, lower semi-continuous cost functions. In particular, this yields a positive answer to Problem 2.25 in C. Villani's book. We emphasize that we do not need any regularity conditions as were imposed in the previous literature.
