Abstract: | A new version of quantum gravity on discrete spaces (simplicial complexes) is proposed. A theory of gravitation interacting with Dirac field is considered. This theory is shown to be free of reparametrization anomaly. The problem of axial gauge anomaly and the associated problem of the doubling of fermion states on a lattice are discussed. |
