On viscosity and fluctuation-dissipation in exclusion processes. (English) Zbl 1157.82355

Summary: We consider the asymmetric simple exclusion process. We review some results in dimension \(d \geq 3\) concerning the fluctuation-dissipation theorem and we prove regularity of viscosity coefficients.
