Stability of eigenvalues and observable diameter in RCD spaces

Jérôme Bertrand, Max Fathi

We study stability of the spectral gap and observable diameter for metricmeasure spaces satisfying the RCD(1, ) condition. We show that if such a space has an almost maxima…

Stability estimates for invariant measures of diffusion processes, with applications to stability of moment measures and Stein kernels

Max Fathi, Dan Mikulincer

We investigate stability of invariant measures of diffusion processes with respect to distances on the coefficients, under an assumption of log-concavity. The method is a var…

Self-improvement of the Bakry-Emery criterion for Poincar{é} inequalities and Wasserstein contraction using variable curvature bounds

Patrick Cattiaux, Max Fathi, Arnaud Guillin

We study Poincar{é} inequalities and long-time behavior for diffusion processes on R^n under a variable curvature lower bound, in the sense of Bakry-Emery. We derive various estima…

Bounds on optimal transport maps onto log-concave measures

Maria Colombo, Max Fathi

We consider strictly log-concave measures, whose bounds degenerate at infinity. We prove that the optimal transport map from the Gaussian onto such a measure is locally Lipschitz,…

Entropic curvature and convergence to equilibrium for mean-field dynamics on discrete spaces

Matthias Erbar, Max Fathi, André Schlichting

We consider non-linear evolution equations arising from mean-field limits of particle systems on discrete spaces. We investigate a notion of curvature bounds for these dynamics bas…

A proof of the Caffarelli contraction theorem via entropic regularization

Max Fathi, Nathael Gozlan, Maxime Prodhomme

We give a new proof of the Caffarelli contraction theorem, which states that the Brenier optimal transport map sending the standard Gaussian measure onto a uniformly log-concave pr…
