摘要：
A new criterion is proposed for linearizing many-body equations of motion which is well defined and is related to a stationary principle. The method is applied to the problem of correlation in a narrow s band and the results differ considerably from Hubbard's treatment of this problem. © 1968 The American Physical Society.
