ASYMPTOTIC FORM OF THE PROPER SELF-ENERGY FUNCTION IN MANY-PARTICLE SYSTEMS,

Abstract

The asymptotic form at high frequencies of the reciprocal of a two-time thermodynamic Green's function is shown to be a constant. This constant is expressed as the exact expectation value of a second (functional) derivative of the Hamiltonian. (Author)
