Geometry and holography of AdS 2 times S squared: towards the field theory dual
The paper seeks a superconformal quantum mechanics dual to supersymmetric AdS2xS2 solutions. It proposes that this dual is organized over a two-dimensional lattice of cells in a space $\Sigma$. The authors identify specific non-Abelian T-duals of known geometries (like AdS3xS2xCY2) that fit this structure, leading to a field theory description via quiver diagrams and baryon vertices.
