In this paper we formulate a dynamical ﬂuctuation theory for stationary non equilibrium states (SNS) which covers situations in a nonlinear hydrodynamic regime and is veriﬁed explicitly in stochastic models of interacting particles. In our theory a crucial role is played by the time reversed dynamics. Our results include the modiﬁcation of the Onsager–Machlup theory in the SNS, a general Hamilton–Jacobi equation for the macroscopic entropy and a non equilibrium, non linear ﬂuctuation…
