Abstract

We summarize the results and the ideas in 1707.06152, 1707.06154, 1807.07768 where new warped AdS₃ backgrounds are derived in massive IIA string theory by uplifting exact solutions in \mathcal N=1, d=7 and \mathcal N=(1,1), d=6 gauged supergravities. These solutions are respectively asymptotically AdS₇ and AdS₆ and they are related to the D2-D4-NS5-D6-D8 brane intersection. We provide a particular supergravity solution in 10d describing this bound state and we discuss the relations between its near-horizon geometry and the uplifts from 6d and 7d. Then we give the holographic interpretation of these AdS₃ warped backgrounds in terms of \mathcal N=(0,4) defect SCFT₂ within the \mathcal N=(1,0) SCFT₆ and the \mathcal N=2 SCFT₅.
