“…gave an apposite account of the present disparity with a particular bent on their development of the so‐called time‐neutral and time aneutral probabilities of decohering histories covering quantum mechanics and cosmology. For in‐depth discussions on the relevant physical and philosophical work, see the excellent anthology: Time's Arrows Today, in particular the introduction by the editor Savitt 6. In short one acknowledges the following possible “arrows”: …”

“…In addition, as the standard nonrelativistic many‐particle Schrödinger equation is time‐invariant, see more below, any system‐apparatus setup contains interactions between relevant degrees of freedom such that any time irreversibility claim in reality amounts to unmatching levels of descriptions of the system and its environment. Although modern studies of decoherence9 aim at proving that classical theory derives from quantum mechanics, there also appears nonconsensical contentions regarding appropriate master equations and their general properties 6, 8, 10…”

The field of chemical and physical processes, using principal microscopic techniques, should today allegedly be identified as a fundamental branch of physics. The discipline, by tradition known as chemical physics, is undergoing rapid progress. This assessment, illustrated by the advances presented at this Congress, is characterized by modern developments and novel trends with a concrete bearing on original theoretical understanding, with the possibility to go beyond traditional interpretations and explanations. In this vein, we do not only consider nonrelativistic treatments of various types of molecules including interactions between these and polymers, theoretical examinations of chemical reactions, surface states and interface states, disordered phenomena etc., but also recent progress together with non-Hermitean extensions to quantum mechanics and statistical mechanics. The latter leads to a united edifice of theoretical constructions including the law of self-reference, which emerges in analogy with the illustrious G€ odel theorem(s) of mathematical logic, that is, the assertion of the inherent limitations of all nontrivial axiomatic systems. The current development begets the foundation of temporal processes and associated invariance principles including the valuation of the various arrows of time. The present conjugate operator array formulation supports the possible gravitational origin of molecular chirality and other principal symmetry violations.

“…We do not attempt here to add any considerations to this difficult and, as said, controversial subject. We simply list in the references [50,54,55,135,135,136,161,[183][184][185][186][187][188][189][190][191][192][193][194][195] some works on the matter which we have selected. As commented by Sklar [4], Nicolai S. Krylov (the Russian scientist unfortunately prematurely deceased) was developing an extremely insightful and careful foundational study of nonequilibrium statistical mechanics [29].…”

It is reviewed what can be considered as the present research trends in what regards to the construction of an ensemble formalism -Gibbs' style -for the case of far-from-equilibrium systems. The main questions involved are presented accompanied with brief discussions. The construction of a nonequilibrium statistical operator is described and its applications commented, and, particularly, it is presented the derivation of an Irreversible Thermodynamics based on the statistical foundations that the nonequilibrium ensemble formalism provides.
