摘要
The solution of the generalized master equation for a macroscopic insulated system is studied in the limit t → + ∞. Using the theory of holomorphic operators in finite-dimensional linear spaces, the spectral properties of the kernel of the G.M.E. are analyzed. It is shown that, under proper conditions, the asymptotic expectation values of the macro-observables are given by the microcanonical (or more generally poly-microcanonical) ensemble. © 1969.
