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.21 pages, typo in references correctedHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyHigh Energy Physics - Latticetext
