Description
The talk will include a general introduction to the main ideas of the Asymptotic Safety approach to quantum gravity. This program aims at finding an acceptable quantum field theory of gravity and spacetime geometry which complies with a number of indispensable physical principles such as Hilbert space positivity and background independence in addition to (nonperturbative) renormalizability. We discuss some of these requirements in a simplified two-dimensional setting where the tools of conformal field theory are available.
