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.About:

Entropy Dissipation Semi-Discretization Schemes for Fokker–Planck Equations
TL;DR: In this paper, a new semi-discretization scheme was proposed to approximate nonlinear Fokker-Planck equations by exploiting the gradient flow structures with respect to the 2-Wasserstein metric in the space of probability densities.

Kinetic modeling of alcohol consumption
Giacomo Dimarco,Giuseppe Toscani +1 more
TL;DR: In this article, the microscopic variation of alcohol consumption of agents around a universal \emph{social} accepted value of consumption, is built up introducing as main criterion for consumption a suitable value function in the spirit of the prospect theory of Kahneman and Twersky.

Isoperimetric inequality under Measure-Contraction property
TL;DR: In this paper, it was shown that if ( X, d, m ) is an essentially non-branching metric measure space with m ( X ) = 1, having Ricci curvature bounded from below by K and dimension bounded above by N ∈ ( 1, ∞ ), understood as a synthetic condition called Measure-Contraction property, then a sharp isoperimetric inequality a la Levy-Gromov holds true.

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
Vladimir I. Arnold,Boris Khesin +1 more
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.
