摘要：

A new stationary property of the grand canonical potential is presented. This property is used to define a class of self-consistent approximations which is particularly appropriate for the so-called ladder approximation. The conditions which guarantee self-consistency are only sufficient. A comparison is made with the already-known stationary properties related to Hartree-Fock and randomphase approximations. Remarks are made on the possibility of a collective excitation associated with the formalism.
