Abstract

It is shown that the Pohlmeyer map of a sigma -model with a toric two-dimensional target space naturally leads to the 'sausage' metric. We then elaborate the trigonometric deformation of the CPn-1-model, proving that its T-dual metric is Kahler and solves the Ricci flow equation. Finally, we discuss a relation between flag manifold sigma-models and Toda field theories.
