2D Lorentzian Gravity as 2D Euclidean Gravity with Ising Spins [PDF]
arXiv, 1996 We suggest a generalization of the dynamical triangulation approach to quantum gravity with both timelike and spacelike edges, which can serve as a toy model for quantum gravity in the Lorentz sector in two dimensions. It is possible to consider the model in a purely Lorentzian sector or to relax this constraint and allow local signature changing moves.
