Trace anomaly and infrared cutoffs
Tim R. Morris, Roberto Percacci
The Effective Average Action is a form of effective action which depends on a cutoff scale suppressing the contribution of low momentum modes in the functional integral. It reduces…
Quantum gravity, renormalizability and diffeomorphism invariance
Tim R. Morris
We show that the Wilsonian renormalization group (RG) provides a natural regularisation of the Quantum Master Equation such that to first order the BRST algebra closes on local fun…
Perturbatively renormalizable quantum gravity
Tim R. Morris
The Wilsonian renormalization group (RG) requires Euclidean signature. The conformal factor of the metric then has a wrong-sign kinetic term, which has a profound effect on its RG…
Renormalization group properties of the conformal mode of a torus
Matthew P. Kellett, Tim R. Morris
The Wilsonian renormalization group properties of the conformal factor of the metric are profoundly altered by the fact that it has a wrong-sign kinetic term. If couplings are chos…
Renormalization group properties of the conformal sector: towards perturbatively renormalizable quantum gravity
Tim R. Morris
The Wilsonian renormalization group (RG) requires Euclidean signature. The conformal factor of the metric then has a wrong-sign kinetic term, which has a profound effect on its RG…
