CFT dualities involving large 2 d N = 4 superconformal symmetry

  author={Jan de Boer and Andrea Pasquinucci and Kostas Skenderis},
We study the duality between string theory on AdS3 × S × S and twodimensional conformal theories with large N = 4 superconformal algebra Aγ. We discuss configurations of intersecting branes which give rise to such near-horizon geometries. We compute the Kaluza-Klein spectrum and propose that the boundary superconformal theory can be described by a sigma model on a suitable symmetric product space with a particular choice of anti-symmetric two-form.
