2-POINT FUNCTIONS IN 4D DYNAMICAL TRIANGULATION

In the dynamical triangulation model of 4D Euclidean quantum gravity w e measure two-point functions of the scalar curvature as a function of the geodesic distance. To get the correlations it turns out that we n eed to subtract a squared one-point function which, although this seem s paradoxical, depends on the distance. At the transition and in the e longated phase we observe a power law behaviour, while in the crumpled phase we cannot find a simple function to describe it.
