# Ultraviolet fixed point and generalized flow equation of quantum gravity

@article{Lauscher2001UltravioletFP, title={Ultraviolet fixed point and generalized flow equation of quantum gravity}, author={Oliver Lauscher and Martin Reuter}, journal={Physical Review D}, year={2001}, volume={65}, pages={025013} }

A new exact renormalization group equation for the effective average action of Euclidean quantum gravity is constructed. It is formulated in terms of the component fields appearing in the transverse-traceless decomposition of the metric. It facilitates both the construction of an appropriate infrared cutoff and the projection of the renormalization group flow onto a large class of truncated parameter spaces. The Einstein-Hilbert truncation is investigated in detail and the fixed point structure…
