A perturbative approach to the non-perturbative renormalization group — •Omar Zanusso — Radboud University, Nijmegen, The Netherlands

We show that the functional renormalization group, also known as non-perturbative renormalization group, admits a perturbative solution and show explicitly the scheme transformation that relates it to the MS method. We then define a scheme, inspired by perturbation theory, that within the functional renormalization group provides manifestly universal results for the beta functions.
