The essential prerequisites for this course are a knowledge of Hilbert space theory and the calculus of functions of several variables.
Partial differential equations arise in the mathematical modelling of many physical, chemical and biological phenomena. Indeed, they play a crucial role in many diverse subject areas, such as fluid dynamics, electromagnetism, material science, astrophysics and financial modelling, for example. Typically, the equations under consideration are so complicated that their solution may not be determined by purely analytical techniques; instead one has to resort to computing numerical approximations to the unknown analytical solution.
This course is devoted to a particular class of numerical techniques for determining the approximate solution of partial differential equations: finite element methods. Here, we will provide an introduction to their mathematical theory, with special emphasis on theoretical and practical issues such as accuracy, reliability, efficiency and adaptivity.
The aim of this course is to introduce the basic theory of finite element methods for the numerical approximation of partial differential equations and provide a good basis for those students who wish to pursue the study of more advanced topics.
To learn about the mathematical theory of finite element methods for partial differential equations.
To understand the theory of weak solutions to elliptic partial differential equations.
To provide analytical techniques for deriving optimal a priori and a posteriori error bounds.
To understand how to efficiently implement finite element methods.
The ability to apply the techniques developed in this course to a large variety of partial differential equations.
The importance of partial differential equations in all areas of science and engineering makes this course an essential prerequisite for any student wishing to pursue a career in applied mathematics.

The final assessment of this module will consist of 10% coursework and 90% from a three hour examination during the Summer exam period. The 10% coursework contribution will be determined by students' solutions to coursework problems. The examination paper will contain 6 questions with full marks on the paper obtainable from 4 complete answers.
