Abstract

We use exceptional field theory as a tool to work out the full non-linear reduction ansaetze for the AdS₅× S⁵ compactification of IIB supergravity and its non-compact counterparts in which the sphere S⁵ is replaced by the inhomogeneous hyperboloidal space H^p,q. The resulting theories are the maximal 5D supergravities with gauge groups SO(p,q). They are consistent truncations in the sense that every solution of 5D supergravity lifts to a solution of IIB supergravity. In particular, every stationary point and every holographic RG flow of the scalar potentials for the compact and non-compact 5D gaugings directly lift to solutions of IIB supergravity.
