Abstract
We show that Euclidean three-dimensional gravity coupled to a Gaussian scalar massive matter field in the first-order dreibein formalism gives a quantum theory which has a finite perturbative expansion around a nonvanishing background. We also discuss a possible mechanism to generate a nontrivial background metric starting from Rovelli-Smolin loop observables.
