• This is an area of comparatively recent development which still possesses potential for growth.

#### Content

• Nonlinear wave equations.
• Progressive wave solutions.
• Backlund transformations for Sine Gordon equation.
• Backlund transformations for KdV equation.
• Conservation laws integrable systems.
• Hirota's method.
• The Nonlinear Schrodinger equation.
• The inverse scattering method.
• The inverse scattering method: two component equations.
• Toda equations.
• Integrability.

#### Learning Outcomes

Subject-specific Knowledge:
• By the end of the module students will:
• be able to solve complex, unpredictable and specialised problems in Solitons.
• have an understanding of specialised and complex theoretical mathematics in the field of Solitons.
• have mastered a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas:
• Nonlinear wave equations.
• Progressive wave equations.
• Backlund transformations for the sine-Gordon equation and the KdV equation.
• Conservation laws in integrable systems.
• Hirota's method.
• The nonlinear Schrodinger equation.
Subject-specific Skills:
• In addition students will have highly specialised and advanced mathematical skills in the following areas: Modelling, Spatial awareness.
Key Skills:

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
• Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
• Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
• The end-of-year examination assesses the knowledge acquired and the ability to solve complex and specialised problems.
