“…Extending further this relation, it has been argued that in a suitable limit, the generating functional for the boundary correlators of singleton composite field is reproduced by the anti-de Sitter supergravity action [9,10]. The conjecture was further explored in [11,12,13,14,15,16,17,18]. Moreover, models with lower world-volume supersymmetries started to be explored [19,20,21,22].…”
