Teleparallel gravity on the lattice
arXiv:hep-lat/0311036 · doi:10.1016/j.physletb.2004.01.001
Abstract
We consider quantum gravity model with the squared curvature action. We construct lattice discretization of the model (both on hypercubic and simplicial lattices) starting from its teleparallel equivalent. The resulting lattice models have the actions that are bounded from below while Einstein equations (without matter) appear in their classical limit.
