Description
Abstract: I will show that flag manifold sigma-models (including CP^{n−1}, Grassmannian models as special cases) and their trigonometric/elliptic deformations may be cast in the form of gauged bosonic Gross-Neveu-type systems. Quantum mechanically the gauging is violated by chiral anomalies, which may be cancelled by adding fermions. I conjecture that such models are integrable and check that the trigonometrically deformed geometries satisfy the generalized Ricci flow equations.
