Description
In the renormalization group approach, it is known that inessential
couplings could be removed by the field redefinitions. Recently it is
pointed out that the quadratic curvature terms fall into this class of
operators, and next cubic term is irrelevant. This suggests that the
Einstein and cosmological term is enough to define asymptotically safe
quantum gravity for pure gravity. Here we extend the study to the case
when the matter is present.
