A note on Talagrand's transportation inequality and logarithmic Sobolev inequality

Probability 2008-10-31 v1 Functional Analysis

Abstract

We give by simple arguments sufficient conditions, so called Lyapunov conditions, for Talagrand's transportation information inequality and for the logarithmic Sobolev inequality. Those sufficient conditions work even in the case where the Bakry-Emery curvature is not lower bounded. Several new examples are provided.
