Generalised structures for N=1 AdS backgrounds

Abstract

We expand upon a claim made in a recent paper [arXiv: 1411.5721] that generic minimally supersymmetric AdS backgrounds of warped flux compactifications of Type II and M theory can be understood as satisfying a straightforward weak integrability condition in the language of E-d(d) x R+ generalised geometry. Namely, they are spaces admitting a generalised G-structure set by the Killing spinor and with constant singlet generalised intrinsic torsion.
