Loop Corrections to Supergravity on AdS5 x S5

We consider the four-point correlator of the stress-energy tensor multiplet in N = 4 super Yang-Mills theory. In the planar limit and at large't Hooft coupling, such a correlator is given by the corresponding holographic correlation function in IIB supergravity on AdS(5) x S-5. We consider subleading corrections in the number of colors, i.e., order 1/N-4, at large't Hooft coupling. This corresponds to loop corrections to the supergravity result. Consistency conditions, most notably, crossing symmetry, constrain the form of such corrections and lead to a complete determination of the spectrum of leading-twist intermediate operators.
