| Aim: To describe physically important non-linear wave phenomena. |
| Contents: Derivation of non-linear partial differential equations from hydrodynamics, optics, solid state physics, molecular dynamics, and neurobiology. Solitary waves as a balance between nonlinearity and dispersion or between nonlinearity and dissipation. Solitary waves and solitons, non-linear interactions, decomposition into solitons and radiation, and conservation theorems. Technological and biological applications of solitary waves. Analytical and numerical methods. Generalized separation of variables. Bäcklund-transformations, inverse scattering techniques, perturbation theory and similarity solutions. Nonlinear diffusion as a paradigm for nonlinear effects in neurobiology. Spatio-temporal competition between order and chaos. Examples of recent research. |
