Resumen de Transport-entropy and functional forms of Blaschke–Santaló inequalities

Matthieu Fradelizi, Nathael Gozlan, Shay Sadovsky, Simon Zugmeyer

• We explore alternative functional or transport-entropy formulations of the Blaschke–Santaló inequality. In particular, we obtain new Blaschke–Santaló inequalities for s-concave functions. We also obtain new sharp symmetrized transport-entropy inequalities for a large class of spherically invariant probability measures, including the uniform measure on the unit Euclidean sphere and generalized Cauchy and Barenblatt distributions.
