Description
Renormalization Group flow in Quantum Einstein Gravity shows gauge and parametrization dependence in quantities such as beta functions and generating functionals.
Using a proper-time regulated flow equation for a Wilsonian effective action, we investigate the properties of the non-Gaussian fixed point in both the Background Field gauge and the Physical gauges, employing linear and exponential parametrizations for the fluctuation.
