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 | Abstract: | In 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. | Source: | arXiv, gr-qc/0401093 | Services: | Forum | Review | PDF | Favorites |
