Physical Review D
Starting from ultraviolet fixed point we study infrared behavior of quantum Weyl gravity in terms of functional RG flow equation. To do so, we employ two classes of Bach-flat backgrounds, namely maximally symmetric spacetimes and Ricci-flat backgrounds in the improved one-loop scheme. We show, that in the absence of matter fields and with a topological term included, the effective action exhibits dynamical breaking of scale symmetry. In particular, it is shown that apart from genuine IR fixeddoi:10.1103/physrevd.101.044050 fatcat:pbbgvqs2afballvx4idzgimcam
