On N = 8 supergravity in AdS5 and N = 4 superconformal Yang-Mills theory Original Research Article

We discuss the spectrum of states of IIB supergravity on AdS5 × 5 in a manifest SU(2,24) invariant setting. The boundary fields are described in terms of N = 4 superconformal Yang-Mills theory and the proposed correspondence between supergravity in AdS5 and superconformal invariant singleton theory at the boundary is formulated in a N = 4 superfield covariant language.
