Abstract
The renormalization group flow is presented for the two-dimensional sine–Gordon model within the framework of the functional renormalization group method by including the wave-function renormalization constant. The Kosterlitz–Thouless–Berezinski type phase structure is recovered as the interpolating scaling law between two competing IR attractive area of the global renormalization group flow.
