In the simplest setting, such a bound amounts to a transport-information inequality involving the L∞-Wasserstein metric and the relative L∞-Fisher information. We show that this inequality can be sharpened significantly in situations where the involved densities are anisotropic. Our proof is based on probabilistic techniques using Langevin dynamics. As an application of these results, we obtain sharp exponential rates of convergence in Fisher’s infinitesimal model from quantitative genetics, generalising recent results by Calvez, Poyato, and Santambrogio in dimension 1 to arbitrary dimensions.","lang":"eng"}],"status":"public","doi":"10.1214/25-aap2162","intvolume":" 35","article_type":"original","volume":35,"department":[{"_id":"JaMa"}],"external_id":{"arxiv":["2402.04151"]},"author":[{"id":"4E6DC800-AE37-11E9-AC72-31CAE5697425","first_name":"Kseniia","last_name":"Khudiakova","orcid":"0000-0002-6246-1465","full_name":"Khudiakova, Kseniia"},{"id":"4C5696CE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0845-1338","last_name":"Maas","full_name":"Maas, Jan","first_name":"Jan"},{"full_name":"Pedrotti, Francesco","last_name":"Pedrotti","first_name":"Francesco","id":"d3ac8ac6-dc8d-11ea-abe3-e2a9628c4c3c"}],"citation":{"short":"K.
