Abstract [en]

Among the possible superalgebras that contain the AdS3 isometries, two interesting possibilities are the exceptional F (4) and G(3). Their R-symmetry is respectively SO(7) and G(2), and the amount of supersymmetry N = 8 and N = 7. We find that there exist two (locally) unique solutions in type IIA supergravity that realize these superalgebras, and we provide their analytic expressions. In both cases, the internal space is obtained by a round six-sphere fibred over an interval, with an O8-plane at one end. The R-symmetry is the symmetry group of the sphere; in the G(3) case, it is broken to G(2) by fluxes. We also find several numerical N = 1 solutions with G(2) flavor symmetry, with various localized sources, including O2-planes and O8-planes.
