Abstract

We investigate the construction of a large class of classical solutions to the nonabelian Grassmannian sigma models in two Euclidean space-time dimensions and also discuss the problem of uniqueness. Some spectral types of solutions have interesting features when represented in the framework of the Riemann-Hilbert problem.
