nLab Poisson-Lie T-duality

Idea

What has come to be called nonabelian T-duality (de la Ossa-Quevedo 1992) or Poisson-Lie T-Duality (due to Klimcik-Ševera 1995, von Unge 02) is a generalization of T-duality from fiber bundles equipped with an abelian group of isometries (torus bundles) to those with a nonabelian group of isometries.

Poisson-Lie T-duality may also be made manifest at the level of type II supergravity in the framework of double field theory on group manifolds. Using this framework both the NS/NS sector and the R/R sector are captured, and this allows to derive the transformation of the RR fields for full Poisson-Lie T-duality (Hassler 17).

As a partial duality of string theory

While ordinary abelian T-duality is supposedly a full duality in string theory, in particular in that it is an equivalence on the string perturbation series to all orders of the squared string length/Regge slope $\alpha'$ and the string coupling constant $g_s$, it was early on shown by Giveon & Roček 1993 that there are topological obstructions at higher genus for non-abelian T-duality, letting it break down in higher orders of $g_s$; and already a genus-0 (tree level) it breaks down for the open string (i.e. on punctured disks) at some order of $\alpha'$.

But see Hassler 20, Borsato-Wulff 20.
