Query: Towards 4-point correlation functions of any 1/2-BPS operators from
  supergravity   The quartic effective action for Kaluza-Klein modes that arises upon
compactification of type IIB supergravity on the five-sphere S^5 is a starting
point for computing the four-point correlation functions of arbitrary weight
1/2-BPS operators in N=4 super Yang-Mills theory in the supergravity
approximation. The apparent structure of this action is rather involved, in
particular it contains quartic terms with four derivatives which cannot be
removed by field redefinitions. By exhibiting intricate identities between
certain integrals involving spherical harmonics of S^5 we show that the net
contribution of these four-derivative terms to the effective action vanishes.
Our result is in agreement with and provides further support to the recent
conjecture on the Mellin space representation of the four-point correlation
function of any 1/2-BPS operators in the supergravity approximation.
