Abstract
New and simpler forms are presented of the closure of the analytical solution of the Ornstein—Zernike equation for the general case consisting of a sum of M Yukawa exponentials with factorizable coefficients in terms of an M × M scaling matrix γ (Blum, L., Vericat, F., and Herrera, J. N., 1992, J. statist. Phys., 66, 249) are presented. The general solution is given in terms of M(M—1) symmetry relations and M boundary conditions. The general form for the multicomponent case is obtained. For only one component the closure for n = 1, …, M is
