The enhanced Sanov theorem and propagation of chaos

Probability 2019-04-23 v2

Abstract

We establish a Sanov type large deviation principle for an ensemble of interacting Brownian rough paths. As application a large deviations for the (kk-layer, enhanced) empirical measure of weakly interacting diffusions is obtained. This in turn implies a propagation of chaos result in rough path spaces and allows for a robust subsequent analysis of the particle system and its McKean-Vlasov type limit, as shown in two corollaries.
