On the absence of localized curvature in the weak-coupling phase of quantum gravity

Abstract
In the weak field expansion of euclidean quantum gravity, an analysis of the Wilson loops in terms of the gauge group, , shows that the correspondent statistical system does not develope any configuration with localized curvature at low temperature. Such a ``non-local'' behavior contrasts strongly with that of usual gauge fields. We point out a possible relation between this result and those of the numerical simulations of quantum Regge Calculus. We also give a general quantum formula for the static potential energy of the gravitational interaction of two masses, which is compatible with the mentioned vacuum structure.
