摘要：

Employing the homotopy method we have obtained the complete set of real solutions to the equations of the restricted Hartree-Fock method as well as the full set of solutions to the equations of the coupled-cluster-with-doubles method for the H4 and P4 models broadly applied in various many-electron studies. These ate the first global results obtained so far for any formulations of the Hartree-Fock and coupled-cluster methods when applied to realistic models. [S0031-9007(98)06772-6].
