Abstract Nonlinear Noisy Leaky Integrate and Fire (NNLIF) models for neurons networks can be written as Fokker-Planck-Kolmogorov equations on the probability density of neurons, the …
We consider non-negative solutions of the fast diffusion equation ut= Δ um with m∈(0, 1) in the Euclidean space\mathbb R^ d, d≧ 3, and study the asymptotic behavior of a natural …
The aim of this paper is to give a characterization of the dimension free concentration of measure phenomenon in terms of transportation-cost inequalities. We apply this theorem to …

We develop the optimal transportation approach to modified log-Sobolev inequalities and to isoperimetric inequalities. Various sufficient conditions for such inequalities are given. Some …
This paper is devoted to the study of probability measures with heavy tails. Using the Lyapunov function approach we prove that such measures satisfy different kind of functional …

We initiate a systematic study of intrinsic dimensional versions of classical functional inequalities which capture refined properties of the underlying objects. We focus on model …

In this paper, we consider Poincaré inequalities for non-Euclidean metrics on Rd. These inequalities enable us to derive precise dimension free concentration inequalities for …
I Merad, S Gaïffas - arXiv preprint arXiv:2306.11497, 2023 - arxiv.org
We consider the optimization of a smooth and strongly convex objective using constant step- size stochastic gradient descent (SGD) and study its properties through the prism of Markov …
