As a new approach to supergravity, an action containing only vierbein and Rarita-Schwinger fields (V/suba//sub mu/ and psi/sub mu/) is presented together with supersymmetry transformations for these… Expand

A new class of ${R}^{2}$ type of actions without ghosts and tachyons is found in which both the vierbein field ${{e}_{\ensuremath{\mu}}}^{a}$ and the spin connection… Expand
