[en] The superpotential for the n-step soliton solution is derived for an axially symmetric, static solution of σ models by using the appropriately modified inverse scattering method of Belinsky and Zakharov. Finite-energy solutions are constructed by the method

[en] In this paper it is shown how time-dependent, cylindrically symmetric solutions can be generated for the class of SU(N) principal σ models. The superpotential for the n-step solution is derived using the inverse-scattering method of Belinsky and Zakharov

[en] The equations for the most general axially symmetric ansatz are derived for SU(2) monopoles in the Bogomol'ny-Prasad-Sommerfield limit. The symmetries of these equations are described. The existence of an infinite parameter invariance group is pointed out. (Auth.)

[en] The superpotential for n-step soliton is derived in the case of an arbitrary dimensional projector for axially symmetric, static solution of nonlinear principal SU(N)σ-models. This is done by using an inverse scattering method developed by Belinski and Zakharov. Finite energy solutions are constructed for all SU(N) one soliton solutions generated by a single step

[en] The generalization of Neugebauer's Baecklund transformation is given for the axially symmetric SU(N) Bogomolny equations. An analogue of the Neugebauer-Kramer mapping is constructed for the SU(3) case. (orig.)
