Deformed $σ$-models, Ricci flow and Toda field theories

Dmitri Bykov, Dieter Lust

英文摘要:

It is shown that the Pohlmeyer map of a $σ$-model with a toric two-dimensional target space naturally leads to the `sausage' metric. We then elaborate the trigonometric deformation of the $\mathrm{CP}^{n-1}$-model, proving that its $T$-dual metric is Kähler and solves the Ricci flow equation. Finally, we discuss a relation between flag manifold $σ$-models and Toda field theories.
