Exact RG flow equations and quantum gravity
Abstract We discuss the different forms of the functional RG equation and their relation to each other. In particular we suggest a generalized background field version that is close in spirit to the Polchinski equation as an alternative to the Wetterich equation to study Weinberg’s asymptotic safety...
