Asymptotic Safety

The following pages are meant as an informal introduction to asymptotic safety and as a guide to the literature.

The Asymptotic Safety FAQs   
These FAQs are now quite out of date.
They may still serve as a general introduction, but they do not reflect the current state of the field.

The situation as of summer 2017 is described in

my book on quantum gravity and asymptotic safety

Another book by Reuter and Saueressig

Asymptotic Safety bibliography 1976-2019
a relatively complete annotated bibliography on the subject, in roughly chronological order, including a list of papers on closely related arguments. *No longer updated*
