Abstract
We present a renormalization group approach to the renormaliza- tion theory of $\varphy^4_4$, 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 the $n!$-bounds.File allegati a questo prodotto
