3D Lorentzian Quantum Gravity from the asymmetric ABAB matrix model
J. Ambjorn, J. Jurkiewicz, R. Loll +1
The asymmetric ABAB-matrix model describes the transfer matrix of three-dimensional Lorentzian quantum gravity. We study perturbatively the scaling of the ABAB-matrix model in the…

Lorentzian and Euclidean Quantum Gravity - Analytical and Numerical Results
J. Ambjorn, J. Jurkiewicz, R. Loll
We review some recent attempts to extract information about the nature of quantum gravity, with and without matter, by quantum field theoretical methods. More specifically, we work…
