G. Grahovski (Institute for Nuclear Research and Nuclear Energy, Sofia, Bulgaria), R. I. Ivanov, (Department of Mathematical Physics, National University of Ireland-Galway, Galway, | Abstract: | The reductions of the integrable N-wave type equations solvable by the inverse scattering method with the generalized Zakharov-Shabat systems L and related to some simple Lie algebra g are analyzed. The Zakharov- Shabat dressing method is extended to the case when g is an orthogonal algebra. Several types of one soliton solutions of the corresponding N- wave equations and their reductions are studied. We show that to each soliton solution one can relate a (semi-)simple subalgebra of g. We illustrate our results by 4-wave equations related to so(5) which find applications in Stockes-anti-Stockes wave generation. | Source: | arXiv, nlin.SI/0009034 | Services: | Forum | Review | PDF | Favorites |
