Characterization of Talagrand's transport-entropy inequalities in metric spaces
Nathaël Gozlan, Cyril Roberto, Paul-Marie Samson
We give a characterization of transport-entropy inequalities in metric spaces. As an application we deduce that such inequalities are stable under bounded perturbation (Holley-Stro…

A new characterization of Talagrand's transport-entropy inequalities and applications
Nathael Gozlan, Cyril Roberto, Paul-Marie Samson
We show that Talagrand's transport inequality is equivalent to a restricted logarithmic Sobolev inequality. This result clarifies the links between these two important functional i…
