Some of us might be interested by what Percacci has to say about AsymSafe theories. He goes beyond simple AS gravity, considers a combined theory with standard matter, the significance of scale-invariance at the fixed points, and (to me) surprising tie-ins with other theory.(adsbygoogle = window.adsbygoogle || []).push({});

A short introduction to asymptotic safety

R. Percacci

(Submitted on 28 Oct 2011)

I discuss the notion of asymptotic safety and possible applications to quantum field theories of gravity and matter.

18 pages. In the proceedings of the conference "Time and matter", Budva, Montenegro, October 2010.

====================

The paper is not merely a brief introductory overview of what many here are already familiar with regarding AS gravity. Percacci has evidently been thinking more about AS.

He also has some curious papers in the bibliography---like this for instance:
