Quantitative concentration inequalities on sample path space for mean field interaction
ESAIM: Probability and Statistics, Tome 14 (2010), pp. 192-209.

We consider the approximation of a mean field stochastic process by a large interacting particle system. We derive non-asymptotic large deviation bounds measuring the concentration of the empirical measure of the paths of the particles around the law of the process. The method is based on a coupling argument, strong integrability estimates on the paths in Hölder norm, and a general concentration result for the empirical measure of identically distributed independent paths.
