---|

#### Prerequisites

- Complex Analysis II (MATH2011) AND Analysis in Many Variables II (MATH2031).

#### Corequisites

- None.

#### Excluded Combination of Modules

#### Aims

- To provide an introduction to solvable problems in nonlinear partial differential equations which have a physical application.
- 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 in 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 novel and/or complex problems in Solitons.
- have a systematic and coherent understanding of theoretical mathematics in the field of Solitons.
- have acquired coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas:
- Nonlinear wave equations.
- Progressive wave solutions.
- 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 specialised mathematical skills in the following areas which can be used with minimal guidance: 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 predictable and unpredictable problems.
