摘要: Many suggested approximations for the ensemble averaged Green function of a disordered system are not analytically acceptable. Here Kraichnan's (1961) idea using 'realizable' is explored and generalized. The method used to prove that self-consistent cluster multiple scattering approximation in theory alloys analytic, result which both practical conceptual importance.
