Antisymmetric tensor field on $AdS_5$

By using the Hamiltonian version of the AdS/CFT correspondence, we compute the two-point Green function of a local operator in D=4 ${\cal N}=4$ super Yang-Mills theory, which corresponds to a massive antisymmetric tensor field of the second rank on the $AdS_{5}$ background. We discuss the conformal transformations induced on the boundary by isometries of $AdS_{5}$.
