Abelian Hypermultiplet Gaugings and BPS Vacua in N = 2 Supergravity

Understand

We analyze the gauging of Abelian isometries on the hypermultiplet scalar manifolds of N = 2 supergravity in four dimensions.

• This involves a study of symmetric special quaternionic-K\"ahler manifolds, building on the work of de Wit and Van Proeyen.
• In particular we compute the general set of Killing prepotentials and associated compensators for these manifolds manifolds.
• This allows us to glean new insights about AdS 4 vacua which preserve the full N = 2 supersymmetry as well as BPS static black hole horizons.
