Three-point functions of chiral operators in D = 4 , N = 4 SYM at large N

We study all three-point functions of normalized chiral operators in D -4, J -4, U(N) supersymmetric Yang-Mills theory in the large N limit.We compute them for small 't Hooft coupling A = 9YM^ ^ 1 using free field theory and at strong coupling A = gY M N ^> 1 using the AdS/CFT correspondence.Surprisingly, we find the same answers in the two limits.We conjecture that at least for large N the exact answers are independent of A.
