Canonical analysis of the BCEA topological matter model coupled to gravitation in (2+1) dimensions
Laurent Freidel, R. B. Mann, Eugeniu M. Popescu
We consider a topological field theory derived from the Chern - Simons action in (2+1) dimensions with the I(ISO(2,1)) group,and we investigate in detail the canonical structure of…

Ponzano-Regge model revisited II: Equivalence with Chern-Simons
Laurent Freidel, David Louapre
We provide a mathematical definition of the gauge fixed Ponzano-Regge model showing that it gives a measure on the space of flat connections whose volume is well defined. We then s…

Ponzano-Regge model revisited I: Gauge fixing, observables and interacting spinning particles
Laurent Freidel, David Louapre
We show how to properly gauge fix all the symmetries of the Ponzano-Regge model for 3D quantum gravity. This amounts to do explicit finite computations for transition amplitudes. W…
