The soliton spectrum (massive and massless) of a family of integrable models with local U
(1) and U (1)⊗ U (1) symmetries is studied. These models represent relevant integrable …

The algebraic conditions that specific gauged G/H-WZW model have to satisfy in order to
give rise to Non-Abelian Toda models with singular metric with or without torsion are found …

We study the symmetries of the soliton spectrum of a pair of T-dual integrable models,
invariant under global SL (2) q⊗ U (1) transformations. They represent an integrable …
