On the Measure of Simplicial Quantum Gravity in Four Dimensions
arXiv:hep-lat/9309008
Abstract
We study quantum gravity in the path-integral formulation using the Regge calculus. In spite of the unbounded gravitational action the existence of an entropy-dominated phase is confirmed. The influence of various types of measures on this phase structure is investigated and our results are compared with those obtained by dynamical triangulation.
