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.

Bounding relative entropy by the relative entropy of local specifications in product spaces

K. Marton
- 26 Jul 2009 - 
TL;DR: In this paper, an inequality between relative entropy and the sum of average conditional relative entropies of the following form was proved: for any density function $p^n(x^n)$ on $\Bbb R^n$, $D(pn||q^n)\leq Const.

Hamilton-Jacobi equations on graph and applications

Yan Shu
TL;DR: In this paper, the authors introduce a notion of gradient and an infimal convolution operator that extend properties of solutions of Hamilton Jacobi equations to more general spaces, in particular to graphs.

Transportation inequalities for Markov kernels and their applications

TL;DR: In this paper, the authors studied the relationship between functional inequalities for a Markov kernel on a metric space X and inequalities of transportation distances on the space of probability measures P(X), and showed that contraction inequalities for these divergences are equivalent to reverse logarithmic Sobolev and Wang Harnack inequalities.

Simulated annealing from continuum to discretization: a convergence analysis via the Eyring--Kramers law

Wenpin Tang, +1 more
- 03 Feb 2021 - 
TL;DR: In this paper, the convergence rate of continuous-time simulated annealing and its discretization for approximating the global optimum of a given function $f$ was studied and it was shown that the tail probability of the model is polynomial in time (resp in cumulative step size).

One-Dimensional Fokker–Planck Equations and Functional Inequalities for Heavy Tailed Densities

TL;DR: In this paper , the problem of trend to equilibrium for one-dimensional Fokker-Planck equations modeling socio-economic problems, and functional inequalities of the type of Poincaré, Wirtinger and logarithmic Sobolev, with weight, for probability densities with polynomial tails are discussed.

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.
