Non-perturbative renormalization: a new way (1312.7526v2)
Published 29 Dec 2013 in hep-th and hep-ph
Abstract: The notion of non-perturbative renormalization is discussed and extended. Within the extended picture, a new non-perturbative representation for the generating functional of Green functions of quantum field theories is suggested. It is argued that the new expression agrees with the standard renormalized perturbation theory if the latter is renormalized in an appropriate renormalization scheme.
