Abstract: Gravity theory is a gauge theory of spin 2 field, and gauge theories of higher spin fields can be constructed on AdS spaces including interactions. Recently, Gaberdiel and Gopakumar proposed that a large N minimal model is dual to a bosonic sub-sector of the higher spin supergravity theory of Prokushkin and Vasiliev on 3 dimensional AdS space. Here we would like to propose a supersymmetric version of the duality, where N=2 CP_N Kazama-Suzuki model corresponds to the full higher spin supergravity theory. The conjecture is based on symmetry considerations and comparison of the bulk partition function with the conformal field theory.
