Abstract: (SISSA)
We review recent developments in the study of the AdS/CFT correspondence in low dimensions, focusing on the construction of AdS3/CFT2 and AdS2/CFT1 dual pairs in massive Type IIA string theory. We start discussing the AdS3 × 𝑆2 × CY2 × 𝐼 solutions to massive IIA supergravity with N = (0, 4) supersymmetry constructed in [1]. We review the 2d CFTs dual to these solutions, together with their defect interpretation as surface defects within 5d xed point theories living in D4-D8 bound states. Next, we discuss the AdS2 × 𝑆3 × CY2 × 𝐼 solutions with N = 4 supersymmetry constructed in [2]. We discuss the superconformal quantum mechanics dual to these solutions, that we interpret in terms of line defects realised as D0-D4 baryon vertices in 5d Sp(N) xed point theories. We review a particular example in this class of solutions, constructed through non-Abelian T-duality with respect to a non-compact isometry group, and discuss the possible embedding of a 3d black hole geometry constructed long ago via non-Abelian T-duality within this solution.Note:
