Intrinsic Vertex Regularization and Renormalization in ${\varphi }^4$ Field Theory

Abstract

Based upon the intrinsic relation between the divergent lower point functions and the convergent higher point ones in the renormalizable quantum field theories, we propose a new method for regularization and renormalization in QFT. As an example, we renormalize the ${\varphi }^4$ theory at the one loop order by means of this method.
