Jr. Madureira et al., FLUX OPERATORS OF MICRODYNAMICAL QUANTITIES IN A NONEQUILIBRIUM STATISTICAL ENSEMBLE FORMALISM, Brazilian journal of physics, 28(2), 1998, pp. 122-131
It is shown how the closure condition for the set of kinetic equations
in Zubarev's Nonequilibrium Statistical Operator Method introduces a
series of fluxes of a reference set of densities. These fluxes are the
average values, over a Gibbs-like nonequilibrium generalized grand-ca
nonical ensemble, of Hermitian operators for fluxes defined at the mic
roscopic-mechanical level. The equations of evolution for these fluxes
(or equivalently for their conjugated Lagrange multipliers) are descr
ibed.
