ANTI--DE-SITTER-CFT CORRESPONDENCE IN 3-DIMENSIONAL SUPERGRAVITY - ART. NO. 085020

Anti-de Sitter supergravity models are considered in three dimensions. Precise asymptotic conditions involving a chiral projection are given on the Rarita-Schwinger fields. Together with the known boundary cond itions on the bosonic fields, these ensure that the asymptotic symmetr y algebra is the superconformal algebra. The classical central charge is computed and found to be equal to the one of pure gravity. It is al so indicated that the asymptotic degrees of freedom are described by 2 D ''induced supergravity'' and that the boundary conditions ''transmut e'' the non-vanishing components of the WZW supercurrent into the supe rcharges.
