ACM40690 Survey of Appl and Comp Math

Academic Year 2023/2024

This module gives a survey of advanced mathematical methods and their application to problems in physics and more generally, in science and engineering. The aim of the module is to equip students to be well-rounded applied mathematicians, capable of tackling problems using closed-form solutions in certain asymptotic limits.

Topics will be drawn from the following (non-exhaustive) list:
[Review of complex analysis] Cauchy-Riemann conditions, Cauchy's integral theorem, calculus of residues, harmonic functions, Jensen's formula.
[Laplace transforms] Definition, examples, properties, and inversion via the Bromwich contour.
[Asymptotic methods for integrals] Laplace's method, Watson's lemma, steepest-descent method,
[Writing the solution of an ODE as a contour integral] and the evaluation of the same in asymptotic limits where the steepest-descent method can be used; Airy functions.
[Singular perturbation theory] The WKB approximation in the far field and near turning points, applications of WKB theory in Quantum Mechanics and Fluid Mechanics.
[Special functions] Frobenius's theorem, independent solutions, applications involving special functions.

Approaches to Teaching and Learning:
Lectures, enquiry and problem-based learning.

These activities constitute the basis for the student’s learning, by engaging the student in actual hard work: listening, writing, studying, solving problems and discussing problems with peers and lecturer.
