2-dimensional nonlinear sigma models: zero curvature and Poisson structureIn this chapter some aspects of two-dimensional nonlinear sigma models are discussed. The solutions to the field equations are (pseudo-)harmonic maps of two-dimensional Minkowski space into some homogeneous Riemannian manifolds.
