Description
The gravitational asymptotic safety program is a promising candidate for a quantum theory of the gravitational interactions. Traditionally, many investigations have been carried out in an Euclidean setting and the transition to Lorentzian signature computations has started only recently. In this talk, I will give a pedagogical introduction to the key elements of asymptotic safety before reviewing the various routes taken towards extending the program to Lorentzian signature. I will then zoom in on asymptotic safety based on the ADM-formalism, which introduces a natural time-direction and provides natural connections to Cosmology and Causal Dynamical Triangulations.
