Scheme dependence and universality in the functional renormalization group
arXiv:1310.7625 · doi:10.1103/PhysRevD.90.027701
Abstract
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.
