A dual formulation of supergravity-matter theories

Understand

Generating supersymmetric AdS solutions in non-minimal supergravity in four dimensions is notoriously difficult.

• Indeed, it is a longstanding lore that such solutions exist only for old minimal supergravity.
• In this paper, we construct a dual formulation for general N=1 supergravity-matter systems that avoids the problem.
• In the case of pure supergravity without a cosmological constant, it coincides with the usual non-minimal (n=-1) supergravity, but in the presence of matter (or a cosmological constant) our formulation differs considerably.
