Spin cube models of quantum gravity


We describe spin cube models of quantum gravity which are based on Poincare 2-group representations labeled by positive real numbers. Depending on how one imposes the General Relativity constraints, one can obtain a spin foam model with the edge-length constraints or a Regge model. The corresponding effective actions have classical limits which are given by the Regge action.
