TLDR
In this paper, it was shown that transport inequalities, similar to the one derived by M. Talagrand (1996, Geom. Funct. Anal. 6, 587-600) for the Gaussian measure, are implied by logarithmic Sobolev inequalities.

Convexity inequalities and optimal transport of infinite-dimensional measures

TL;DR: In this paper, the authors generalize Talagrand's inequality in the theory of optimal transport and give some applications of their result in particular for a couple of transportation mappings.

Transportation-information inequalities for Markov processes (II) : relations with other functional inequalities

TL;DR: For a symmetric markov process, the authors showed that the spectral gap in the space of Lipschitz functions for a diffusion process implies the usual transportation inequalities (W_pH) and the corresponding concentration inequalities for the invariant measure.

Transportation inequalities for stochastic differential equations of pure jumps

TL;DR: In this article, a differentielle stochastique de pur saut, bien que l’inegalite de Poincare ne soit pas valide en general, nous pouvons quand meme etablir, sous la condition de dissipativite, des inegalites de transport W1H pour sa mesure invariante et pour sa loi (au niveau de processus) sur l'espace des trajectoires cadlag, muni de la metrique L1 ou d'une

Polar Factorization and Monotone Rearrangement of Vector-Valued Functions

TL;DR: In this paper, it was shown that for every vector-valued function u Lp(X, p; Rd) there is a unique polar factorization u = V$.s, where $ is a convex function defined on R and s is a measure-preserving mapping from (x, p) into (Q, I. I), provided that u is nondegenerate.

The geometry of dissipative evolution equations: the porous medium equation

TL;DR: In this paper, the authors show that the porous medium equation has a gradient flow structure which is both physically and mathematically natural, and they use the intuition and the calculus of Riemannian geometry to quantify this asymptotic behavior.

Topological methods in hydrodynamics

TL;DR: A group theoretical approach to hydrodynamics is proposed in this article, where the authors consider the hydrodynamic geometry of diffeomorphism groups and the principle of least action implies that the motion of a fluid is described by geodesics on the group in the right-invariant Riemannian metric given by the kinetic energy.
