Limiting density of states for quantum rotator model

I. A. Koshovets


Abstract: The concept of the limiting density of states is introduced for operators associated with a dynamical system, and some smoothness properties of the density are studied. The limiting density of states for the evolution operator of a quantum rotator is found explicitly.
