摘要：
A formulation of quantum gravity with a gauge-invariant cutoff is given by transcribing MacDowell and Mansouri's formulation of general relativity onto a Wilson lattice. The weak coupling and strong coupling expansions are developed. The strong coupling expansion reveals a typical strong coupling phase with short range order, confinement (of spin) and asymptotic freedom. If the lattice theory has a second-order phase transition, then the continuum theory may be well-defined. © 1979.
