NONEQUILIBRIUM STATISTICAL-MECHANICS NEAR-EQUILIBRIUM - COMPUTING HIGHER-ORDER TERMS

Using Sinai-Ruelle-Bowen measures to describe nonequilibrium steady st ates, one can in principle compute the coefficients of expansions arou nd equilibrium. We discuss how this can be done in practice, and how t he results correspond to the zero noise limit when there is a stochast ic perturbation. The approach used is formal rather than rigorous.
