    "abstract": "We derive the classical algebra of the non-local conserved charges in the\nO(N) WZNW model and analyze its dependence on the coupling constant of the\nWess-Zumino term. As in the non-linear sigma model, we find cubic deformations\nof the O(N) affine algebra. The surprising result is that the cubic algebra of\nthe WZNW non-local charges does not obey the Jacobi identity, thus opposing our\nexpectations from the known Yangian symmetry of this model.",
