Abstract
Three methods are developed for the calculation of the inverse Green's function of alloys. One is a perturbation method using an expansion in powers of the concentration; the other two are nonperturbational and one of these is self-consistent. Methods are developed for lattices with both short- and long-range ordering.Keywords
