Equivalence of Two Nonequilibrium Ensembles Based on Maximum Entropy Principle

Abstract

The relation between two versions of so called non-equilibrium statistical operator method (NESOM), NESOM-1 due to Zubarev (1961) and NESOM-2 due to Zubarev and Kalashnikov (1970), is considered. It is proved that, once the balance equations of NESOM-2 are satisfied, those of NESOM-1 will be satisfied with the same set of the macro-parameters. The proof uses the convexity-type inequalities, and does not involve any assumptions additional to the rationales behind NESOM. However, converse statement cannot be proved within this technique. An extension of the proof to overall equivalence of the two nonequilibrium ensembles is discussed. This arXiv publication is dedicated to the memory of Dmitrii Nikolaevich Zubarev
