Abstract
AbstractIt is shown that the Pohlmeyer map of a $$\sigma $$
σ
-model with a toric two-dimensional target space naturally leads to the ‘sausage’ metric. We then elaborate the trigonometric deformation of the $$\mathbb {CP}^{n-1}$$

-model, proving that its T-dual metric is Kähler and solves the Ricci flow equation. Finally, we discuss a relation between flag manifold $$\sigma $$
σ
-models and Toda field theories.
