Abstract
We present a renormalization group approach to the renormalization theory ofΦ 44 , using techniques that have been introduced and used in previous papers and that lead to very simple methods to bound the coefficients of the effective potential and of the Schwinger functions. The main aim of this paper is to show how one can in this way obtain then!-bounds.
