On the Running Gauge Coupling Constant in the Exact Renormalization Group
Jun-Ichi Sumi
In this paper, we investigate the beta-function of the gauge coupling constant () of the gauged four-fermi theory in the Exact Renormalization Group (ERG) framework. It seems th…

Scheme Dependence of the Wilsonian Effective Action and Sharp Cutoff Limit of the Flow Equation
Jun-Ichi Sumi, Wataru Souma, Ken-Ichi Aoki +2
The cutoff scheme dependence in the several formulations of the Exact Renormalization Group (ERG) is investigated. It is shown that the cutoff scheme dependence of the Wilsonian ef…
