Phys. Rev. D 63, 064010 (2001) [15 pages]Holographic formulation of quantum supergravity
Yi Ling * and Lee Smolin † Received 30 October 2000; published 12 February 2001 We show that N=1 supergravity with a cosmological constant can be expressed as constrained topological field theory based on the supergroup Osp(1|4). The theory is then extended to include timelike boundaries with finite spatial area. Consistent boundary conditions are found which induce a boundary theory based on a supersymmetric Chern-Simons theory. The boundary state space is constructed from states of the boundary supersymmetric Chern-Simons theory on the punctured two sphere and naturally satisfies the Bekenstein bound, where area is measured by the area operator of quantum supergravity. ©2001 The American Physical Society
