The Principal chiral model as an integrable systemsics under the name of chiral fields . These are maps with values in nonlinear manifolds such as Lie groups, Grassmannians, projective spaces, spheres, Stiefel manifolds, etc; therefore the equations defining these maps are nonlinear. The two-dimensional case can be solved exactly (with the excep

Harmonic maps via Adler—Kostant—Symes theoryons (soliton equations) and their relationship to classical problems in differential geometry. It has been shown in a series of recent papers that constant mean and Gauss curvature surfaces, Willmore surfaces, minimal surfaces in spheres and projective spaces and generall

Loop group actions on harmonic maps and their applications into Lie groups (or symmetric spaces), and their applications to the study of deformations of harmonic maps. The classification theory of harmonic maps of Riemann spheres into the .-dimensional standard sphere .. was given by Calabi (, Chern , Barbosa ), see . It was shown that any h
