Gauge and Cutoff Function Dependence of the Ultraviolet Fixed Point in Quantum Gravity
Wataru Souma
The exact renormalization group equation for pure quantum gravity is derived for an arbitrary gauge parameter in the space-time dimension . This equation is given by a non-lin…

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…
