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…

Space-time foam in 2D and the sum over topologies
R. Loll, W. Westra
It is well-known that the sum over topologies in quantum gravity is ill-defined, due to a super-exponential growth of the number of geometries as a function of the space-time volum…
