“…It was argued that a similar story applies to SU(3) U(1)×U (1) , although it was later found [17] that these SU(3)invariant solutions actually have two shape parameters. The effective four-dimensional theory corresponding to an expansion in terms of left-invariant forms on these cosets was studied in [19,20]. It was found in [21] that this expansion actually corresponds to a consistent reduction.…”

We scan for massive type IIA SU(3)-structure compactifications of the type AdS 4 × CP 3 with internal symmetry group SO(4). This group acts on CP 3 with cohomogeneity one, so that one would expect new non-homogeneous solutions. We find however that all such solutions enhance their symmetry group to Sp(2) and form, in fact, the homogeneous family first described in [1]. This is in accordance with [2], which argues from the CFT-side that although new vacua with SO(4) symmetry group and N = 2 supersymmetry should exist, they fall outside our ansatz of strict SU(3)-structure, and instead have genuine SU(3)×SU(3)-structure. We do find that the SO(4)-invariant description, which singles out one preferential direction in the internal space, is well-adapted for describing the embedding of AdS 4 -filling supersymmetric D8-branes on both the original ABJM configuration as its massive Sp(2)-symmetric deformations. Supersymmetry requires these D-branes to be of the coisotropic type, which means in particular that their world-volume gauge field must be non-trivial.
