Abstract

The inverse scattering transform technique of Belinskii-Zakharov for the integration of nonlinear sigma model equations is reviewed. N-soliton solutions of the principal chiral field equations axe given. The explicit two-complex pole soliton solutions of vacuum and electro-vacuum Ernst equations are constructed.
