On the cutoff identification and the quantum improvement in asymptotically safe gravity
Applying the exact renormalization group method to search the non–Gaussian fixed points of gravitational coupling, is frequently followed by two steps: cutoff identification and improvement. Although there are various models for identifying the cutoff momentum by some physical length, saving the gen...
