Description

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.
