MA321 (Calculus and Mathematical Modelling), MA322 (Proofs and Numbers), MA323 (Matrices and Probability) at Stage 1 and MA552 (Analysis), MA553 (Linear Algebra), MA588 (Mathematical Techniques and Differential Equations) at Stage 2, or students must have studied material equivalent to that covered in these modules.





The lectures will introduce students to asymptotic and perturbation methods for the approximate evaluation of integrals and to obtain approximations for solutions of ordinary differential equations. These methods are widely used in the study of physically significant differential equations which arise in Applied Mathematics, Physics and Engineering. The material is chosen so as to demonstrate a range of mathematical techniques available and to illustrate some different applications which are amenable to such analysis.
