The Ponzano-Regge model
John W. Barrett, Ileana Naish-Guzman
The definition of the Ponzano-Regge state-sum model of three-dimensional quantum gravity with a class of local observables is developed. The main definition of the Ponzano-Regge mo…

The Ponzano-Regge model and Reidemeister torsion
John W. Barrett, Ileana Naish-Guzman
The Ponzano-Regge model of three-dimensional quantum gravity is well-defined when the observables satisfy a certain condition involving the twisted cohomology. In this case, the pa…
