Abstract
It is shown that there is no appreciable difference between the results of a method developed by Movaghar, Miller and Bennemann (see abstr. A53027 of 1974) and those of the method of Ishida and Yonezawa (see abstr. A43984 of 1973) for cases in which physically reasonable parameters are chosen. The analytical properties of the Ishida-Yonezawa Green's function equation are examined. It is shown that the parameter used by Movaghar and Miller in a modified hard-core pair correlation function are physically unreasonable.Keywords
