Einstein Gravity in 2+1 Dimensions from a Gauge Model with Symmetry Breaking
arXiv:hep-th/9208034
Abstract
Einstein Gravity in 2+1 dimensions arises as a consequence of the equations of motion of a gauge model in an external metric. Newton's constant appears as an order parameter of a spontaneously broken discrete symmetry. Matter is coupled in a straightforward way.
