✦ Synopsis


The Gibbs and Boltzm~nn description of a system are contrasted for the entropy of a general Markov process. An H theorem is established for the Gibbs entropy. The master equation for non-stationary processes is introduced to initiate a discussion of the p.henomenological equations in the two descriptions. The assumed connection between stationary state fluctuations and irreversible processes is exploited to yield the Nyquist relation for stationary processes.

The problem of the quantum generalization of the classical Nyquist formula is considered as a part of the general problem of the introduction of Langevin sources in the quantum dissipative equations. Two possible forms of the quantum Nyquist formula are discussed. It is demonstrated that the Lamb-Re
