A Hamiltonian Lattice Theory for Homogeneous Curved Spacetimes in 2+1 Dimensions
A. Criscuolo, H. Waelbroeck
We propose an exact Hamiltonian lattice theory for (2+1)-dimensional spacetimes with homogeneous curvature. By gauging away the lattice we find a generalization of the ``polygon re…

Quantization of 2+1 Gravity on the Torus
A. Criscuolo, H. Quevedo, H. Waelbroeck
We use the polygon representation of 2+1--dimensional gravity to explicitly carry out the canonical quantization of a universe with the topology of a torus. The mapping-class-invar…
