Abstract
We remark that an “old fashioned” approach to $\varphi_4^4$ based on perturbation theory leads naturally to the necessity of considering also “antiferromagnetic actions” for the study of the ultraviolet limit. This type of cut-off theories seems to have never been considered.File allegati a questo prodotto
