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.

Concentration of quantum states from quantum functional and Talagrand inequalities

TL;DR: In this paper, the authors introduce quantum generalizations of T1 and T2, making use of appropriate quantum versions of the Wasserstein distances, one recently defined by Carlen and Maas and the other defined by us.

Coarse-graining of non-reversible stochastic differential equations: quantitative results and connections to averaging

TL;DR: This work extends recent results on effective reversible dynamics by conditional expectations to the setting of general non-reversible processes with non-constant diffusion coefficient and proves relative entropy and Wasserstein error estimates for the difference between the time marginals of the effective and original dynamics.

A quantitative log-Sobolev inequality for a two parameter family of functions

TL;DR: In this paper, a sharp, dimension-free stability result for the classical logarithmic Sobolev inequality for a two-parameter family of functions was proved for a certain class of log $C^{1,1}$ functions.

A sharp uniform-in-time error estimate for Stochastic Gradient Langevin Dynamics

Lei Li, +1 more
- 19 Jul 2022 - 
TL;DR: A sharp uniform-in-time error estimate is established for the Stochastic Gradient Langevin Dynamics (SGLD) and an O ( η ) bound is obtained for the distance between the SGLD iteration and the invariant distribution of the Langevin diffusion, in terms of Wasserstein or total variation distances.

A new approach to posterior contraction rates via Wasserstein dynamics

TL;DR: This paper presents a new approach to the classical problem of quantifying posterior contraction rates (PCRs) in Bayesian statistics based on Wasserstein distance, and it leads to two main contributions which improve on the existing literature of PCRs.

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.
