Extended Regge complex for linearized Riemann-Cartan geometry and cohomology

Snorre H. Christiansen, Kaibo Hu, Ting Lin

We show that the cohomology of the Regge complex in three dimensions is isomorphic to ${\mathcal{H}}_{dR}^{\bullet }(\Omega )\otimes \mathcal{R}\mathcal{M}$, the infinitesimal-rigid…
