Renormalization of Lorentzian conformally reduced gravity
CLASSICAL AND QUANTUM GRAVITY（2019）
摘要
The functional renormalization group treatment is presented for the conformally reduced form of the quantum Einstein gravity with Lorentzian signature. It is shown that the model is asymptotically safe. The critical exponents are determined for various types of regulators.
