摘要: We show that the algebra of discretized spatial diffeomorphism constraints in Hamiltonian lattice quantum gravity closes without anomalies limit small spacing. The result holds for arbitrary factor-ordering and a variety different discretizations continuum constraints, thus generalizes an earlier calculation by Renteln.
