QUANTUM EQUATION OF MOTION AND TWO-LOOP CUTOFF RENORMALIZATION FOR [[phi].sup.3] MODEL

QUANTUM EQUATION OF MOTION AND TWO-LOOP CUTOFF RENORMALIZATION FOR [[phi].sup.3] MODEL

A two-loop renormalization of [[phi].sup.3] model effective action is presented by using the background field method and cutoff momentum regularization. A derivation of the quantum equation of motion and its application to the renormalization procedure are also studied. Bibliography: 23 titles.
