Phys. Rev. Lett. 62, 2905–2906 (1989)Superconformal gravity in three dimensions as a gauge theoryReceived 6 March 1989; published in the issue dated 19 June 1989 We discuss the recent formulation of conformal gravity as a first-order Chern-Simons gauge theory and show that N superconformal gravity can be treated analogously for arbitrary N. This formulation unifies the gravitational and O(N) Yang-Mills Chern-Simons actions. © 1989 The American Physical Society URL:
