Спирова Светлана Николаевна
- familiarization with solutions of nonlinear partial differential equations of the soliton type, the study of their characteristic properties and typical dynamics, in contrast to linear and nonlinear dispersive waves
- formation of the basic knowledge and skills applied to the research of properties of soliton-type waves
- awareness of the Inverse Scattering Transform as a nonlinear spectral method for studying wave dynamics
- familiarization with actual scientific problems related to the dynamics of soliton-type waves
- Aware of the basic properties of the KdV equation, can derive the first integrals of the equation, familiar with the properties of the solitons and their collisions, have a broader view on the KdV-type integrable equations and their soliton-type solutions
- Aware of the basic properties of the NLS equation, of the exact solutions bright/gray/dark solutions and breathers, rogue waves, familiar with the concept of the complex amplitude.
- Aware of the main equations of the wave type, able to recognize nonlinear equations and linear equations with dispersion, can write the dispersion relation for a given linear equation with dispersion, can derive the soliton solution as the localized stationary solution
