We investigate the two- and three-point correlation functions of the dyonic
magnon and spike, which correspond to the solitonic string moving in the
Poincare AdS and three-dimensional sphere. We show that the coupling between
two dyonic magnons or spikes together with a marginal scalar operator in the
string theory is exactly the same as one obtained by the RG analysis in the
gauge theory.Comment: 15 pages, no figur
