Abstract
Abstract We study the higher-derivative extension of the functional renormalization group (FRG). We consider FRG equations for a scalar field that consist of terms with higher functional derivatives of the effective action and arbitrary cutoff functions. We show that the ϵ expansion around the Wilson–Fisher fixed point is indeed reproduced by the local potential approximation of the FRG equations.
