The Algebra of Non-Local Charges in Non-Linear Sigma Models
E. Abdalla, M. C. B. Abdalla, J. C. Brunelli +1
We obtain the exact Dirac algebra obeyed by the conserved non-local charges in bosonic non-linear sigma models. Part of the computation is specialized for a symmetry group .…
Off critical current algebras
E. Abdalla, M. C. B. Abdalla, G. Sotkov +1
We discuss the infinite dimensional algebras appearing in integrable perturbations of conformally invariant theories, with special emphasis in the structure of the consequent non-a…
Current Algebra of Super WZNW Models
E. Abdalla, M. C. B. Abdalla, O. H. G. Branco +1
We derive the current algebra of supersymmetric principal chiral models with a Wess-Zumino term. At the critical point one obtains two commuting super Kac-Moody algebra as expected…
