(2 + 1)-dimensional interacting model of two massless spin-2 fields as a bi-gravity model
We propose a new group-theoretical (Chern–Simons) formulation for the bi-metric theory of gravity in (2+1)-dimensional spacetime which describe two interacting massless spin-2 fields. Our model has been formulated in terms of two dreibeins rather than two metrics. We obtain our Chern–Simons gravity...
