Dressing cosets revisited Original Research Article

We present an alternative algebraic derivation of the dual pair of non-linear σ-models based on the ‘dressing cosets’ extension of the Poisson–Lie T-duality (Klimčík and Ševera, 1996 ). Then we generalize the result to dual pairs of Lagrangians not considered in (Klimčík and Ševera, 1996 ). Our generalization turns out to incorporate the dualisable models constructed by Sfetsos (1999) .
