We present the Lagrangian and Hamiltonian of the Born–Infeld model in Cartesian and light cone variables. Using the auto-Backlund transformation, we construct new solutions of the corresponding nonlinear equation. In particular, a “dressed” Bar

We propose a general scheme of application of the Moutard transformation to second-order partial differential equations with two independent variables. A realization of this scheme is given for the nonstationary Schrodinger equation and Fokker–Plan

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
