DESCRIPTION:I will describe a procedure for constructing one-parameter int
 egrable deformations of integrable sigma-models. In the case of the princi
 pal chiral model on G one recovers the Yang-Baxter sigma-model which coinc
 ides with the squashed 3-sphere sigma-model when G = SU(2). When applied t
 o the symmetric space sigma-model on F/G we obtain a new one-parameter fam
 ily of integrable sigma-models. The classical symmetry algebra of the latt
 er is a q-deformation of the symmetries of the symmetric space sigma-model
 . This procedure generalises also to semi-symmetric space sigma-models. We
  use it to construct an integrable deformation of the AdS_5 x S^5 superstr
 ing.
