Résumé : The two forms of generalized master equation derived by Van Hove and by Prigogine and Résibois are examined with the aid of diagrams. Given the random phase initial condition they are shown to equivalent describe the exact asymptotic behaviour of a diagonal element of density matrix. Their interrelation is clarified. Both of the equations exhibit non-Markoffian evolution. Their interrelation is clarified. derived gives valuable hints to the problem in what conditions and in what manner such non-Markoffian equations will be reduced to the usual Markoffian master equations. A few remarks are given on this point. © 1957.
