Instituut voor theoretische fysica, Rijksuniversiteit te Utrecht, Nederland ## Synopsis The 'master equation' describes the behaviour of a macroscopic system in terms of a time dependent probability distribution. It is here shown that, if the initial distribution is concentrated in a small region

Equation (14)
can also be obtained more directly by noting that the equilibrium distribution P(a) = G(a) must satisfy (6).
**) This is of course only correct because we have chosen the special form (6) for the Fokker-Planck equation.

The nonlinear generalization of the theory of Onsager and Machlup presented in a previous paper is extended to the case in which both of even and odd variables exist simultaneously. The generalization of Onsager's principle of least dissipation for the general nonlinear process is presented based o
The present work consist of two parts: In the first part we apply the method of quasilinearization to the differential equation describing the time development of the quantum-mechanical probability density. In this way we derive the master equation without resorting to perturbation theory. In the se
