The local product condition implies cutoff

Francesco Pedrotti, Justin Salez

In the theory of mixing times, a famously wrong conjecture predicts that a sequence of Markov processes exhibits cutoff as soon as the product of their Poincaré constant and mixing…

Entropy-Wasserstein regularization, defective local concentration and a cutoff criterion beyond non-negative curvature

Francesco Pedrotti

Notions of positive curvature have been shown to imply many remarkable properties for Markov processes, in terms, e.g., of regularization effects, functional inequalities, mixing t…

A transport approach to the cutoff phenomenon

Francesco Pedrotti, Justin Salez

Substantial progress has recently been made in the understanding of the cutoff phenomenon for Markov processes, using an information-theoretic statistics known as varentropy [Sal23…

A new cutoff criterion for non-negatively curved chains

Francesco Pedrotti, Justin Salez

The cutoff phenomenon was recently shown to systematically follow from non-negative curvature and the product condition, for all Markov diffusions. The proof crucially relied on a…

Concentration of information on discrete groups

Jonathan Hermon, Xiangying Huang, Francesco Pedrotti +1

Motivated by the Asymptotic Equipartition Property and its recently discovered role in the cutoff phenomenon, we initiate the systematic study of varentropy on discrete groups. Our…

-optimal transport of anisotropic log-concave measures and exponential convergence in Fisher's infinitesimal model

Ksenia A. Khudiakova, Jan Maas, Francesco Pedrotti

We prove upper bounds on the -Wasserstein distance from optimal transport between strongly log-concave probability densities and log-Lipschitz perturbations. In the simpl…

Contractive coupling rates and curvature lower bounds for Markov chains

Francesco Pedrotti

Contractive coupling rates have been recently introduced by Conforti as a tool to establish convex Sobolev inequalities (including modified log-Sobolev and Poincaré inequality) for…
