Abstract
In this paper we report some results on the expectation values of a set of observables introduced for three-dimensional Riemannian quantum gravity with positive cosmological constant, that is, observables in the Turaev–Viro model. Instead of giving a formal description of the observables, we just formulate the paper by examples. This means that we just show how an idea works with particular cases and give a way to compute ‘expectation values’ in general by a topological procedure.
