Abstract: | The well known analogy between the classical distribution function and the quantum mechanical density operator is extended to the cases of joint and conditional probability-distributions. Thus one is led to a generalized definition of correlation and response-functions in quantum systems. The generalization becomes essential if irreversible dynamical laws such as the Wangsness-Bloch equation are considered. |
