on Asymptotic Safety

Asymptotic safety is a nonperturbative generalization of renormalizability, based on the existence of a nontrivial fixed point for the renormalization group flow. After introducing the basic ideas of this approach, I review the present evidence of a gravitational fixed point, discuss some consequences and relations to other approaches to quantum gravity.
