started a bare minimum at Poisson-Lie T-duality, for the moment just so as to have a place to record the two original references

added more references, in particular Ossa-Quevedo 92, which is maybe the first one.

Made “nonabelian T-duality” a redirect

Are you looking at this with regard to Higher T-duality? Any interest in higher non-abelian T-duality for, say, $String(G)$?

Yes and no: The question in the background was whether the “geometric” complement of “topological” 3-spherical T-duality could be Poisson-Lie T-duality for isometry group $SU(2)$. I still don’t know on the math side. But at least the physics contexts do not match: The Poisson-Lie T-duality is based on string sigma-models, while the realization of spherical T-duality that we found replaces strings by 5-branes.
