Prospects for Asymptotic Safety
Speaker(s): Steven Weinberg
Abstract:

Gravitational average action and asymptotic safety: past and future
Speaker(s): Martin Reuter

Asymptotic safety: a review
Speaker(s): Jean Zinn-Justin
Abstract: I shall review on field theory examples, the meaning of the concept of asymptotic safety in the context of low energy effective field theories.

Mechanisms of Asymptotic Safety
Speaker(s): Holger Gies
Abstract:
Date: 05/11/2009 - 3:00 pm

Asymptotic Safety and Resummed Quantum Gravity
Speaker(s): B.F.L. Ward
Abstract: In Weinberg’s asymptotic safety approach to quantum gravity, one has a finite dimensional critical surface for a UV stable fixed point to generate a theory of quantum gravity with a finite number of physical parameters. The task is to demonstrate how this fixed point behavior actually aris... read more

Asymptotic safety and deformed symmetry
Speaker(s): Lee Smolin
Abstract:

Nonperturbative Insights from Causal Dynamical Triangulations
Speaker(s): Renate Loll
Abstract:
Date: 06/11/2009 - 11:00 am

Gravitational fixed points and asymptotic safety from perturbation theory
Speaker(s): Max Niedermaier
Abstract: The fixed point structure of the renormalization flow in Einstein gravity and higher derivative gravity is investigated in terms of the background effective action. Using a covariant operator cutoff that keeps track of powerlike divergences and the transversal-traceless decomposition a construction ... read more
