Non-Abelian T-duality and modular invariance

Two-dimensional σ-models corresponding to coset CFTs of the type (gˆk⊕hˆℓ)/hˆk+ℓ admit a zoom-in limit involving sending one of the levels, say ℓ, to infinity. The result is the non-Abelian T-dual of the WZW model for the algebra gˆk with respect to the vector action of the subalgebra h of g. We exa...
