摘要
We study N = 1 compactification of IIB supergravity to AdS(4). The internal manifold must have SU(2)-structure. By putting some restrictions on the SU(2) torsion classes, we can perform an exhaustive scan of all possible solutions on group manifolds (a priori non compact). We show that sourceless solutions don't exist in our class and that the presence of O5 and O7 orientifolds is mandatory. We also find a new solution and relate it by T-duality to a known type IIA solution with O6 planes.
