### Learning Outcomes

Learning outcomes The study of nonlinear systems has quietly and steadily revolutionized the realm of science over recent years. It is known that for nonlinear systems new structures emerge that have their features and peculiar ways of interacting. Examples of such structures abound in nature and include, amongst others: vortices (like tornadoes), solitons (bits of information used in optical fiber communications, water waves, tsunamis, etc), and chemical reactions. This course is intended as an introduction to the theory and of Nonlinear Waves and their applications. By the end of the course students will be able to: highlight the major differences between linear and nonlinear waves and the special features of solitons. Solve linear waves equations and understand the concept of a dispersion relation. Construct similarity solutions. use the inverse scattering transform and to construct analytical solutions. Search for, analysis and synthesis of data and information, with the use of the necessary technology. Adapting to new situations. Decision-making.

### Syllabus

The linear wave theory, Burgers' equation, the Korteweg-de Vries (KdV) equation, travelling waves and the scattering problem for the KdV equation, the inverse scattering transform and solitons, the nonlinear Schrödinger equation, applications to water waves and optics.
