Abstract

Euclidean quantum gravity in four dimensions is investigated within the Regge calculus by computer simulations. The action is bounded without dimensional terms by fixing the average lattice spacing. We set the scale by a parateter and consider two different pressures. In the low β region we observe a phase with negative curvature and a homogenous distribution of the link lengths independence of the model. The large β region is characterized by inhomogenous link lengths distribution with spikes and positive curvature depending on the measure.
