Scalar Curvature Fluctuations on the Four-Sphere
Sergio M. C. V. Goncalves, Ian G. Moss
Abstract
Two-point functions of the scalar curvature for metric fluctuations on the four-sphere are analysed. The two-point function for points separated by a fixed distance and for metrics of fixed volume is calculated using spacetime foam methods. This result can be used for comparison between the continuum approach to quantum gravity and numerical quantum gravity on the lattice. Pacs numbers: 04.60.Gw, 04.60.Nc, 04.62.+v
