Convergence rate of general entropic optimal transport costs

G Carlier, P Pegon, L Tamanini - Calculus of Variations and Partial …, 2023 - Springer
We investigate the convergence rate of the optimal entropic cost v ε to the optimal transport
cost as the noise parameter ε↓ 0. We show that for a large class of cost functions c on R d× …

Towards a mathematical theory of trajectory inference

H Lavenant, S Zhang, YH Kim… - arXiv preprint arXiv …, 2021 - arxiv.org
We devise a theoretical framework and a numerical method to infer trajectories of a
stochastic process from samples of its temporal marginals. This problem arises in the …

Generalized incompressible flows, multi-marginal transport and Sinkhorn algorithm

JD Benamou, G Carlier, L Nenna - Numerische Mathematik, 2019 - Springer
Starting from Brenier's relaxed formulation of the incompressible Euler equation in terms of
geodesics in the group of measure-preserving diffeomorphisms, we propose a numerical …

Stochastic approaches to deterministic fluid dynamics: a selective review

AB Cruzeiro - Water, 2020 - mdpi.com
We present a stochastic Lagrangian view of fluid dynamics. The velocity solving the
deterministic Navier–Stokes equation is regarded as a mean time derivative taken over …

An entropy minimization approach to second-order variational mean-field games

JD Benamou, G Carlier, S Di Marino… - … Models and Methods in …, 2019 - World Scientific
We propose an entropy minimization viewpoint on variational mean-field games with
diffusion and quadratic Hamiltonian. We carefully analyze the time discretization of such …

Small noise limit and convexity for generalized incompressible flows, Schrödinger problems, and optimal transport

A Baradat, L Monsaingeon - Archive for Rational Mechanics and Analysis, 2020 - Springer
This paper is concerned with six variational problems and their mutual connections: the
quadratic Monge–Kantorovich optimal transport, the Schrödinger problem, Brenier's relaxed …

Nash embedding, shape operator and Navier-Stokes equation on a Riemannian manifold

S Fang - Acta Mathematicae Applicatae Sinica, English Series, 2020 - Springer
What is the suitable Laplace operator on vector fields for the Navier-Stokes equation on a
Riemannian manifold? In this note, by considering Nash embedding, we will try to elucidate …

An application of Pontryagin's principle to Brownian particle engineered equilibration

P Muratore-Ginanneschi, K Schwieger - Entropy, 2017 - mdpi.com
We present a stylized model of controlled equilibration of a small system in a fluctuating
environment. We derive the optimal control equations steering in finite-time the system …

Entropy on the Path Space and Application to Singular Diffusions and Mean-field Models

P Cattiaux - arXiv preprint arXiv:2404.09552, 2024 - arxiv.org
In this paper we introduce a (partly) new approach for the study of McKean-Vlasov
equations, including singular interactions. This approach is based on the relativeentropy on …
