摘要

In this paper we discuss the convergence properties of the iterative solution of the inverse Dyson equation for quasiparticle corrections to HF energy eigenvalues. Especially we show that this iteration converges only if a principal solution exists. In this case it converges exactly to that solution. We show that a solution to which the iteration converges must have a pole strength larger than 1/2 and that this solution must be the one with the largest pole strength, because the pole strength has to have values between 0 and 1, and the sum over all the pole strengths has to equal 1. As an example a tight binding model is discussed. (C) 1996 Academic Press, Inc. [References: 40]
