Title: Lie-admissible structure of statistical mechanics

Abstract

The objective of this paper is to identify the algebraic structure of statistical mechanics for Newtonian systems as they actually occur in nature, that is, with forces nonderivable from a potenial. For this objective, we first review the definition of dissipative forces, nonconservative forces, and, more generally, variationally nonselfadjoint forces, the latter being the forces which violate the integrability conditions for the existence of a potential. We then review Liouville's theorem in its original formulation, and show that this theorem is indeed capable of incorporating variationally nonselfadjoint forces. By using this background, we then pass to the identification of a number of properties of the statistical description of Newtonian systems of the class considered. Our major result consists of the proof of a theorem according to which the time evolution law of densities for the statistical description of variationally nonselfadjoint Newtonian systems can always be represented in terms of brackets verifying the laws of the Lie-admissible algebras. Since these algebras are an algebraic covering of the Lie algebras, the conventional Lie-algebra formulation of statistical mechanics is recovered as a subcase when all forces are derivable from a potential. This result establishes the direct universality of the Lie-admissible algebras in statisticalmore » mechanics, in the sense that these algebras occur without redefinition of the local variables and physical quantities, as well as they hold for all systems of the class considered. We then tackle the problem of quantization of the statistics of dissipative phenomena, with particular reference to an algebraic reinterpretation of the approach by Prigogine and his collaborators. The paper ends with a number of comments indicating the physical relevance of our analysis.« less
