报告摘要：

There is agrowing awareness toward a slow shifting in the foundation of the thermodynamiclaws, from several macroscopic, empirical postulates concerning heat as a formof random motions, to derivable mathematical theorems based on stochasticdynamics of mesoscopic systems. It becomes increasingly clear that a stochasticdynamic description of the Nature is a very effective mathematicalrepresentation of the Reality. In this talk, I shall first introduce thismathematicothermodynamics as a set of mathematical results, and then apply themto two significant problems: (1) The Gibbsian macroscopic isothermal chemicalthermodynamics via a mathematical limit by merely allowing the molecularnumbers to be infinite. (2) A lift of a finite Markov process with irreversiblecycles to an infinite system that establishes, in the long-time limit, theentropy production in the former is equal to the potential energy decrease inthe latter. This result unifies the Clausius’ and Kelvin’s statements of theSecond Law.
