Abstract

For a complete connected Riemannian manifold M let V ∈ C2(M) be such that μ(dx) =e−V(x) vol(dx) is a probability measure on M. Taking μ as reference measure, we derive in-equalities for probability measures on M linking relative entropy, Fisher information, Steindiscrepancy and Wasserstein distance....

Abstract: For a complete connected Riemannian manifold M let V ∈ C2(M) be such that μ(dx) =e−V(x) vol(dx) is a probability measure on M. Taking μ as reference measure, we derive in-equalities for probability measures on M linking relative entropy, Fisher information, Steindiscrepancy and Wasserstein distance. These inequalities strengthen in particular the fa-mous log-Sobolev and transportation-cost inequality and extend the so-called Entropy/Stein-discrepancy/Information (HSI) inequality established by Ledoux, Nourdin and Peccati (2015)for the standard Gaussian measure on Euclidean space to the setting of Riemannian manifolds.
