Topological Two Dimensional Dilaton Supergravity
V. O. Rivelles
Abstract
We present a topological version of two dimensional dilaton supergravity. It is obtained by gauging an extension of the super-Poincaré algebra in two space-time dimensions. This algebra is obtained by an unconventional contraction of the super de Sitter algebra. Besides the generators of the super de Sitter algebra it has one more fermionic generator and two more bosonic generators one of them being a central charge. The gauging of this algebra is performed in the usual way. Unlike some proposals for a dilaton supergravity theory we obtain a model which is non-local in the gravitino field.
