Besides the integer level k and the deformation parameter \u03bb, these models are characterized by the embedding parameter q of the <math><mi>U</mi><mo>(</mo><mn>1</mn><mo>)</mo></math> factor. We show that an axial-vector T-duality persists along the deformations and, therefore, the models are canonically equivalent. We demonstrate integrability even though the space is non-symmetric and compute the RG-flow equations for the parameters \u03bb and q. Our example provides an integrable deformation of the gravitational solution representing a Euclidean three-dimensional black string."
