On the relation between gradient flows and the large-deviation principle, with applications to Markov chains and diffusion

A Mielke, MA Peletier, DRM Renger - Potential Analysis, 2014 - Springer
Motivated by the occurrence in rate functions of time-dependent large-deviation principles,
we study a class of non-negative functions ℒ that induce a flow, given by ℒ (ρ t, ρ ̇ t)= 0 …

Entropic optimal transport: Geometry and large deviations

E Bernton, P Ghosal, M Nutz - Duke Mathematical Journal, 2022 - projecteuclid.org

A formula for the time derivative of the entropic cost and applications

G Conforti, L Tamanini - Journal of Functional Analysis, 2021 - Elsevier
In the recent years the Schrödinger problem has gained a lot of attention because of the
connection, in the small-noise regime, with the Monge-Kantorovich optimal transport …

Convergence rates for regularized optimal transport via quantization

S Eckstein, M Nutz - Mathematics of Operations Research, 2024 - pubsonline.informs.org

Doubly regularized entropic Wasserstein barycenters

L Chizat - arXiv preprint arXiv:2303.11844, 2023 - arxiv.org
