A NONEQUILIBRIUM STATISTICAL GRAND-CANONICAL ENSEMBLE - DESCRIPTION IN TERMS OF FLUX OPERATORS

In the domain of Statistical Mechanics of nonequilibrium-nonlinear (di ssipative) systems based on a generalized Gibbs-Boltzmann ensemble for malism,it may be highlighted the so-called Nonequilibrium Statistical Operator Method, and, particularly, Zubarev's approach. We report here a detailed analysis of a case consisting in a generalized nonequilibr ium grand-canonical ensemble. Its construction requires to introduce b esides the traditional densities of energy and the particle number the ir nonconserving-dissipative fluxes of all order,The description is qu ite appropriate to provide a framework for the construction of a noncl assical thermo-hydrodynamics, which is briefly described.
