Hypocoercivité , inégalité de concentration, temps d'atteinte et fonctions de Lyapunov
Pierre Monmarché
We establish that, for a Markov semi-group, hypocoercivity, i.e. contractivity for a modified norm, implies quantitative deviation bounds for additive functionals of th…

Étude spectrale minutieuse de processus moins indécis que les autres
Pierre Monmarché, Laurent Miclo
In this paper we are looking for quantitative estimates for the convergene to equilibrium of non reversible Markov processes, especialy in short times. The models studied are simpl…
