Improving the effective potential

Abstract
A g ral procedure is presented how to improve the effective potential by using the renormalization group equation (RGE) in the scheme. If one knows the L-loop effective potential and the RGE coefficient functions up to the (L + 1)-loop level, this procedure gives an improved potential which satisfies the RGE and contains all of the leading, nest-to-leading, …, and Lth-to-leading log terms.
