Asymptotically safe f(R)-gravity coupled to matter II: Global solutions
Ultraviolet fixed point functions of the functional renormalisation group equation for f(R)-gravity coupled to matter fields are discussed. The metric is split via the exponential parameterisation into a background metric and a fluctuating part, the former is chosen to be the one of a four-sphere. A...
