This module introduces a selection of mathematical techniques which are applicable in a wide range of scientific applications.
Introduce students to the following areas of mathematics:
Calculus of Variations
Orthogonal Function Expansions
Asymptotic Methods or Geometric Singular Perturbation Theory
Enable students to solve problems related to each of these areas.
Illustrate how these areas of mathematics relate to problems connected to the real world, such as in engineering for example.
|On successful completion of this module: In the area of Variational Methods, students will be able to do some or all of the following: • Derive the Euler-Lagrange equation using the calculus of variations.||KCT|
|Use variational methods to extremise integrals with and without constraints||KCT|
|Use variational methods and the principal of least action to minimise an action functional in Classical Mechanics. Use Noether's Theorem to identify the symmetries of the action and calculate the associated conserved charges.||KCT|
|Use variational methods to extremise multiple integrals over multivariable functions; particularly, to solve for minimal surfaces.||KCT|
|In the area of Orthogonal Functions and Sturm-Liouville Theory, students will be able to do some or all of the following : • Determine whether or not a linear differential operator subject to specific boundary conditions is self-adjoint||KCT|
|Identify a regular, periodic or singular Sturm-Liouville problem, and hence quote the properties of its eigenfunctions and eigenvalues.||KC|
|Transform a second order linear ODEs into Sturm-Liouville form and identify the weight function.||KCT|
|Find the solution of a regular, periodic or singular Sturm-Liouville problem in the form of a generalised series expansion over orthogonal functions.||KCT|
|Derive the recurrence relations for orthogonal polynomial solutions of Sturm-Liouville problems; including Chebyshev, Legendre, Laguerre and Hermite polynomials||KCT|
|Apply Sturm-Liouville theory to solve separable linear PDEs in terms of generalised series expansions over orthogonal functions; particularly, solve the Laplace equation in terms of spherical harmonics.||KCT|
|Use Sturm-Liouville theory to solve inhomogeneous ODEs with boundary conditions by finding a Green's function.||KCT|
|In the area of Integral Transforms, students will be able to do some or all of the following : • Quote and derive the properties of Fourier transforms and inverse Fourier transforms, and Laplace transforms.||KCT|
|Calculate inverse Fourier transforms and inverse Laplace transforms using residue calculus and Jordan's Lemma.||KCT|
|Recognise which integral transform is appropriate to solve a linear ODE or PDE. Use a Fourier transform or Laplace transform to find a solution to the ODE or PDE.||KCT|
|In the area of Perturbation Theory, students will be able to do some or all of the following: • Express the solutions of an algebraic equation in the form of a regular or a singular perturbative expansion in a small parameter.||KCT|
|Express the solution of a differential equation in the form of a perturbative expansion in a small parameter, and determine whether or not the asymptotic nature of the expansion breaks either at a spatial boundary or at late times.||KCT|
|Use the method of matched asymptotic expansions to find the solution of a differential equation, with a boundary layer, in the form of two perturbative expansions inside and outside the boundary layer, which match in an intermediate region.||KCT|
|Use the method of multiple scales to find the solution of a differential equation, with fast and slow time scales, in the form of a perturbative expansion which is valid at late times.||KCT|

Methods of Teaching / Learning
The learning and teaching strategy is designed to provide:
A thorough advanced mathematical techniques which can be applied to problems which have a wide range of applications.
Experience (through demonstration) of critically assessing and determining the appropriate techniques to solve advanced mathematical problems.
The learning and teaching methods include:
3 hours of lectures per week x 11 weeks – module material will be presented on the blackboard/whiteboard and may be supplemented by module notes.
In addition to attending lectures and reading the module notes, students will learn by attempting a wide range of exercises and unassessed coursework problems.
Students will be strongly encouraged to use the books listed as background reading for the module.
The assessment strategy is designed to provide students with an opportunity to demonstrate:
Understanding of the methods and techniques required to solve problems in the topics listed in the module aims.
Subject knowledge through the recall of definitions and theorems, as well as the choice of technique required to solve particular problems.
Analytic ability through the solution of unseen and similar to seen problems in the test and exam.
Thus, the summative assessment for this module consists of:
One two hour examination at the end of Semester 1 – worth 80% of the module mark.
One in-semester test – worth 20% of the module mark.
Formative assessment and feedback
Students will receive written feedback in the form of two marked pieces of unassessed coursework. Additional verbal feedback will be provided by the lecturer at optional weekly tutorials or office-hours.
