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.

Modified logarithmic Sobolev inequalities and transportation inequalities

TL;DR: In this paper, a class of modified logarithmic Sobolev inequalities interpolating between Poincar\'e and LSS inequalities was presented, which are suitable for measures of the type $exp(exp(-|x|^\al)$ or more complex $exp((exp(|x||^ \al\log^\beta(2+|x |))$ ($\al\in]1,2[$ and be\in\dR$) which lead to new concentration inequalities.

The one dimensional free Poincaré inequality

TL;DR: In this article, the authors discuss the natural candidate for the one-dimensional free Poincare inequality in the planar limit of a matrix model and discuss the relations with the other free functional inequalities, namely, the free transportation and Log-Sobolev inequalities.

Talagrand Inequality on Free Path Space and Application to Stochastic Reaction Diffusion Equations

TL;DR: In this article, the transportation cost inequality on the free path space of Markov processes was established by using a split argument due to [1], and the general result was applied to stochastic reaction diffusion equations with random initial values.

Gradient flow structure and exponential decay of the sandwiched Rényi divergence for primitive Lindblad equations with GNS-detailed balance

TL;DR: It is shown that the sandwiched R\'enyi divergence of any order ${\alpha} \in (0, \infty)$ decays exponentially fast under the time-evolution of such a Lindblad equation.

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.
