Abstract

With the use of the modification of the weak energy condition for theories with torsion developed by Hehl, we analyse classical free N = 1 supergravity in the hope that spin‐spin contact interactions may avert singularities, as happens in the neutrinic case. We find that this does not happen, since the appearence of singularities is conditioned by the cosmological model of the gravitino field in consideration. We present a very simple singularity free model for a spatially homogeneous Rarita‐Schwinger field in a Robertson‐Walker spacetime. Copyright © 1989 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
