Non-monotone convergence in the quadratic Wasserstein distance

Probability 2007-05-23 v1

Abstract

We give an easy counter-example to Problem 7.20 from C. Villani's book on mass transport: in general, the quadratic Wasserstein distance between nn-fold normalized convolutions of two given measures fails to decrease monotonically.
