On Strong Integrability of the Dressing Cosets
Résumé
We formulate sufficient conditions for the strong integrability of dressing cosets. We provide several sigma-model backgrounds solving those conditions, some of them are new and some of them were not so far formulated as the dressing cosets. The new models are based on the Drinfeld doubles having the structure of higher-order jet bundles of quadratic Lie groups.
