Generalised fluxes, Yang-Baxter deformations and the O(d,d) structure of non-abelian T-duality

Dieter Lust, David Osten

Based on the construction of Poisson-Lie T-dual $\sigma$-models from a common parent action we study a candidate for the non-abelian respectively Poisson-Lie T-duality group. This group…
