Abstract

In this paper, we prove that the laws of interacting Brownian particlesare characterized as Gibbs fields on pathspace associated to an explicit class ofHamiltonian functionals. More generally, we show that a large class of Gibbsfields on pathspace corresponds to Brownian diffusions. Some applications totime reversal in the stationary and non stationary case are presented.
