Renormalization Theory in Four-Dimensional Scalar Fields (I)
Communication in Mathematical Physics, 100, 545--580, 1985
Abstract: We present a renormalization group approach to the renormalization theory of $\phy_4^4$, 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.
