Asymptotically Safe Quantum Gravity — •Frank Saueressig — Radboud University, Nijmegen, The Netherlands

Weinberg's Asymptotic Safety scenario, building on a non-trivial fixed point of the gravitational renormalization group flow, provides an elegant mechanism to construct a quantum theory of gravity within the framework of quantum field theory. The most important tools for investigating this scenario are functional methods which allow constructing renormalization group flows of a theory without resorting to the expansion in a small parameter or specifying the fundamental action a priori. This talk will give a concise introduction to the gravitational Asymptotic Safety program before reviewing its current status and future perspectives.
