Type of module:

Summary module description:

This module is designed to teach students of mathematics a brief introduction to partial differential equations. Students learn in the class could be helpful for them in subsequent courses and research as well as in their career and in life in the long run.

The Module lead at NUIST is Dr Vahid Darvish.

Aims:

This module is intended to teach students of mathematics fundamental knowledge of partial differential equations.

Assessable learning outcomes:

By the end of the module, it is expected that students will be able to:

1. Solve linear first-order PDE with different methods.

2. Solve the heat equation and use Duhamel’s principle to treat sources in the diffusion equation.

3. Solve the wave equation by using D’ Alembert’s method and be introduced to ideas of causality, domain of dependence, and range of influence.

4. State and apply maximum principles to conclude uniqueness results.

5. Solve wave equations, heat equations, Laplace equations and Helmholtz equations on a finite interval by separation of variables and derive simple Green’s functions.

6. Know the fundamental properties of a solution to the Laplace equations.

7. Use energy methods to give apriori estimates for certain partial differential equations.

8. Classify the 2nd order partial differential equations.

9. Know the basic method of the numeric partial differential equations.

10. Know some basic information about some famous Nonlinear PDEs.

 

Additional outcomes:

By the end of the module, it is expected that students should be able to apply the above skills to further study and research.

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Assessment requirements for a pass:

A mark of 40% overall.

Reassessment arrangements:

One examination paper of 3 hours duration in August/September - the resit module mark will be the higher of the exam mark (100% exam) and the exam mark plus previous coursework marks (70% exam, 30% coursework).
