Title: MEMORY-DEPENDENT CONSTITUTIVE-EQUATIONS IN INFORMATIONAL STATISTICAL THERMODYNAMICS

Abstract: The nonequilibrium Statistical Operator Method, seemingly contained within the scope of Jaynes' Predictive Statistical Mechanics, provides a foundation for irreversible thermodynamics in what is called Informational Statistical Thermodynamics, and within it a way of deriving generalized constitutive equations which contain non-localities on space. Here we present a derivation of these equations of evolution describing how memory effects are incorporated into the theory. We show that the memory kernels in the kinetic coefficients and relaxation times can be expressed in terms of an infinite series of instantaneous collisions integrals, of ever increasing order in the interaction strengths that are related to the slow relaxation processes that develop in the system. The kinetic coefficients are derived on the basis of the Hamiltonian dynamics of the system accompanied by appropriate averages over the nonequilibrium informational statistical ensemble.
