New renormalization procedure for eliminating redundant operators

New renormalization procedure for eliminating redundant operators

A generalized exact renormalization group equation is obtained by using a new renormalization procedure. This equation does not contain redundant operators and therefore enables one to avoid using an uncertain procedure for their exclusion.
