Description
I report on the computation of the 4-point functions of CPO's of weights {2,3,4,5} and {3,4,5,6} in the supergravity approximation. An honest way to do so, according to AdS/CFT correspondence, is to find the on-shell value of the effective action of type IIB supergravity compactified on S^5. These results provide a non-trivial check of the recently conjectured formula for the 4-point function in Mellin space. We discuss the latter together with possible simplifications of the algorithm.
