AB A general class of deformations of integrable sigma-models with symmetricspace F/G target-spaces are found. These deformations involve defining the non-abelianT dual of the sigma-model and then replacing the coupling of the Lagrange multiplierimposing flatness with a gauged F/F WZW model. The original sigma-model is obtainedin the limit of large level. The resulting deformed theories are shown to preserve bothintegrability and the equations-of-motion, but involve a deformation of the symplecticstructure. It is shown that this deformed symplectic structure involves a linear combinationof the original Poisson bracket and a generalization of the Faddeev-Reshetikhin Poissonbracket which we show can be re-expressed as two decoupled F current algebras. It isthen shown that the deformation can be incorporated into the classical model of strings onR×F/G via a generalization of the Pohlmeyer reduction. In this case, in the limit of largesigma-model coupling it is shown that the theory becomes the relativistic symmetric spacesine-Gordon theory. These results point to the existence of a deformation of this kind forthe full Green-Schwarz superstring on AdS5 × S5
