Hypermultiplet gaugings and supersymmetric solutions from 11D and massive IIA supergravity on spaces.

Supersymmetric , and asymptotically black hole solutions are studied in the context of non-minimal supergravity models involving three vector multiplets (STU-model) and Abelian gaugings of the universal hypermultiplet moduli space. Such models correspond to consistent subsectors of the and gauged maximal supergravities that arise from the reduction of 11D and massive IIA supergravity on spaces down to four dimensions. A unified description of all the models is provided in terms of a square-root prepotential and the gauging of a duality-hidden symmetry pair of the universal hypermultiplet. Some aspects of M-theory and massive IIA holography are mentioned in passing.
