The polygon representation of three dimensional gravitation and its
... • Due to the absence of local degrees of freedom, the theory is topological, which is manifest in the first order formalism as we will see in the next section. Among others, this means that one can discretize spacetime, e.g. by means of triangulation, while still keeping the exact set of dynamical v ...
