Mass transportation and contractions

Abstract

According to a celebrated result of L. Caffarelli, every optimal mass transportation mapping pushing forward the standard Gaussian measure onto a log-concave measure $e^{-W}dx$ with $D^{2}W\ge Id$ is 1-Lipschitz. We present a short survey of related results and various applications.
