A geometric approach to correlation inequalities in the plane
TL;DR: In this paper, the authors demontre des inegalites de correlation for des mesures de probabilite a symetrie radiale, and precisement on montre que, parmi la famille des ensembles width-decreasing, le ratio de correlation est minimised par des bandes.

Sharp stability for the Riesz potential
Nicola Fusco,Aldo Pratelli +1 more
TL;DR: In this article, the stability of the ball as maximizer of the Riesz potential among sets of given volumes was proved with sharp exponent of 1/2, and is valid for any dimension and any power.

Diffeomorphic approximation of w 1;1 planar sobolev homeomorphisms
Stanislav Hencl,Aldo Pratelli +1 more
TL;DR: In this paper, the authors show that there exists a sequence of smooth diffeomorphisms converging to a homeomorphism in Euclidean space in a domain W √ 1,1,1 (Omega,\mathbb R^2) and uniformly.

The closure of planar diffeomorphisms in Sobolev spaces
Guido De Philippis,Aldo Pratelli +1 more
TL;DR: In this paper, the authors characterize the weak and strong closure of planar diffeomorphisms in the Sobolev topology and show that they always coincide, and provide sufficient conditions for a planar map to be approximable by diffeomorphic objects in terms of the connectedness of its counter images.

On the continuity of the total cost in the mass transport problem with relativistic cost functions
TL;DR: In this article, the authors considered the mass transport problem in the case of a relativistic cost, and established the continuity of the total cost, together with a general estimate about the directions in which the mass can actually move, under mild assumptions.
