27 Apr 2015  ·  Codello Alessandro, Demmel Maximilian, Zanusso Omar ·

We prove that the functional renormalization group flow equation admits a perturbative solution and show explicitly the scheme transformation that relates it to the standard schemes of perturbation theory. We then define a universal scheme within the functional renormalization group...
