Bianchi identities in simple supergravity

Complete investigation of the Bianchi identities in simple supergravity without third type constraints is carried out. Its results are valid for all kinds of supergravity (minimal, non-minimal, alternative minimal as well as a new formulation with the auxiliary superfield). The holonomy group including scale and chiral transformations is considered. Applications of some general statements similar to the Dragon theorems in extended supergravity theory are discussed.
