High spin limits and non-abelian T-duality
Alexios P. Polychronakos, Konstadinos Sfetsos
The action of the non-abelian T-dual of the WZW model is related to an appropriate gauged WZW action via a limiting procedure. We extend this type of equivalence to general sigma-m…

Solving field equations in non-isometric coset CFT backgrounds
Alexios P. Polychronakos, Konstadinos Sfetsos
The largest known class of gravitational backgrounds with an exact string theoretical description is based on coset G/H CFTs and the corresponding gauged WZW models. These backgrou…
