Observables in 3-dimensional quantum gravity and topological invariants
J.Manuel Garcia-Islas ;
Date 21 Dec 2003
Journal Class.Quant.Grav. 21 (2004) 3933-3952
Subject gr-qc hep-th
AbstractIn this paper we report some results on the expectation values of a set of observables introduced for 3-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.
