Description

In Quantum Gravity, the regulator breaks diffeomorphism symmetry and background independence. In this talk, we reinstate gauge invariance and background independence by a field redefinition at every renormalisation group step and discuss the properties of the resulting Reuter fixed point. Moreover, we show improved stability results for simple gravity-matter systems.
