GENERALIZATION OF THE FLUCTUATION-DISSIPATION THEOREM TO CLASSICAL NONEQUILIBRIUM SYSTEMS WITH ANISOTROPIC TEMPERATURES

The fluctuation-dissipation theorem (FDT) in its kinetic form is generalized to anisotropic none-quilibrium states with more than one temperature. In a pseudoequilibrium, expressions for the generalized response functions and for the generalized correlation functions can be defined that preserve the form of a FDT in the classical limit.
