Noncompact sigma-models: Large N expansion and thermodynamic limit
A. Duncan, M. Niedermaier, P. Weisz
Noncompact SO(1,N) sigma-models are studied in terms of their large N expansion in a lattice formulation in dimensions d \geq 2. Explicit results for the spin and current two-point…

The Asymptotic Safety Scenario in Quantum Gravity -- An Introduction
M. Niedermaier
The asymptotic safety scenario in quantum gravity is reviewed, according to which a renormalizable quantum theory of the gravitational field is feasible which reconciles asymptotic…

Dimensionally reduced gravity theories are asymptotically safe
M. Niedermaier
4D Einstein gravity coupled to scalars and abelian gauge fields in its 2-Killing vector reduction is shown to be quasi-renormalizable to all loop orders at the expense of introduci…
