3D Lorentzian Quantum Gravity from the asymmetric ABAB matrix model
arXiv:hep-th/0311072
Abstract
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 neighbourhood of its symmetric solution and deduce the associated renormalization of three-dimensional Lorentzian quantum gravity.
