#### Prerequisites

- Analysis in Many Variables II (MATH2031) and one extra 20 credit Level 2 mathematics module; alternatively Analysis in Many Variables II (MATH2031) and Core Mathematics B1 (if taken in Year 2).

#### Corequisites

- One 20 credit Level 3 mathematics module.

#### Excluded Combination of Modules

- Partial Differential Equations IV (MATH4041)

#### Aims

- To develop a basic understanding of the theory and methods of solution for Partial Differential Equations.
- To develop a basic understanding of the ideas of approximate (numerical) solution to certain Partial Differential Equations.

#### Content

- First order equations and characteristics. Conservation laws.
- Systems of first-order equations, conservation law and Riemann invariants.
- Hyperbolic systems and discontinuous derivatives. Acceleration waves.
- Classification of general second order quasi-linear equations and reduction to standard form for each type (elliptic, parabolic and hyperbolic).
- Energy methods for parabolic equations. Well-posedness.
- Maximum principles for parabolic equations.
- Finite difference solution to parabolic and elliptic equations.
- Stability and convergence for solution to finite difference equations.
- Iterative methods of solving Ax=b.

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will: be able to solve problems in Partial Differential Equations;
- have an understanding of theoretical mathematics in the field of Partial Differential Equations;
- have mastered a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: solution of hyperbolic equations and systems.
- classification of second order PDEs, and their solution;
- maximum principles for parabolic equation;
- energy estimates for a parabolic equation;
- finite difference methods for PDEs.

Subject-specific Skills:

- Students will have highly specialized and advanced mathematical skills in the following areas: Modelling, Numerical Mathematics.

Key Skills:

- Students will have an appreciation of Partial Differential Equations in the real world and how to solve them.

#### 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.
