Generalised structures for \( \mathcal{N}=1 \) AdS backgrounds. (English) Zbl 1390.81420

Summary: We expand upon a claim made in a recent paper [the first author et al., Classical Quantum Gravity 33, No. 12, Article ID 125026, 27 p. (2016; Zbl 1342.83346)] 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 \( {E}_{d(d)}\times \mathbb R^+\) generalised geometry. Namely, they are spaces admitting a generalised \(G\)-structure set by the Killing spinor and with constant singlet generalised intrinsic torsion.
