Abstract |
Weinberg's asymptotic safety scenario proposes that gravity constitutes a consistent and predictive Quantum Field Theory within Wilson’s generalized framework of renormalization. The key ingredient in the construction is a non-trivial fixed point of the gravitational renormalization group flow which controls the UV behavior of the theory and renders it safe from unphysical divergences. This talk gives a pedagogical introduction to the main tool available for investigating this conjecture, the functional renormalization group equation for gravity, before reviewing the evidence supporting this conjecture. In particular, it will discuss the “Universal RG Machine”, a systematic and algebraic algorithm for constructing non-perturbative approximate solutions of the gravitational RG flow. |
