The formal exact solutions of the cluster variation method applied to the single occupancy system have been obtained. The reduced distribution functions and free energy expression turn out to be exactly the same as the Born–Green–Yvon (BGY) solutions, thus implying the cluster variation method and B...

Zusammenfassung:The formal exact solutions of the cluster variation method applied to the single occupancy system have been obtained. The reduced distribution functions and free energy expression turn out to be exactly the same as the Born–Green–Yvon (BGY) solutions, thus implying the cluster variation method and BGY approach to the single occupancy system are equivalent.
