摘要：

The matrix Darboux transformation is applied to an auxiliary problem of the classical Wess-Zumino-Novikov-Witten model. One- and two-soliton solutions are written explicitly, and a matrix expression for the N-soliton solution is given. Discrete symmetries of the WZNW model are analyzed, and a solution of the linearized equation of motion is obtained. © 2009 Springer Science+Business Media, Inc.
