Some cubic couplings in type IIB supergravity on AdS(5)xS(5) and three-point functions in four-dimensional super Yang-Mills theory at large N - art. no. 064009

All cubic couplings in type IIB supergravity on AdS(5) x S-5 that involve t wo scalar fields s(1) that are mixtures of the five form field strength on S-5 and the trace of the graviton on S-5 are derived by using the covariant equations of motion and the quadratic action for type IIB supergravity on AdS(5) x S-5. All corresponding three-point functions in SYM4 are calculate d in the supergravity approximation It is pointed out that the scalars s(1) correspond not to the chiral primary operators in the N = 4 SYM but rather to a proper extension of the operators.
