Summary  Our understanding of the fundamental processes of the natural world is based to a large extent on ordinary and partial differential equations (ODEs and PDEs). This course extends the study of ODEs and PDEs started in earlier courses by introducing several ideas and techniques that enable the construction of explicit exact or approximate solutions. Assessment is by assignments and final examination.

Course description 
Integral transforms often provide solutions through integral representations. The integrals involved are nontrivial and need to be approximated using asymptotic expansions that take advantage of large or small parameters. The first part of the course discusses both integral transform methods and asymptotic techniques for the approximation of the resulting integrals. A second part introduces asymptotic techniques for the direct approximation of solution of ODEs. The final part of the course focuses on PDEs. It introduces important techniques for the solution of several classes of linear PDEs (heat and wave equation) and nonlinear PDEs (firstorder). The concept of shock waves, familiar from supersonic flight and fluid flow, is introduced. The fitting of shock and expansion waves into the solution of nonlinear hyperbolic pde's is dealt with in detail. Examples are drawn from traffic flow, supersonic fluid flow and erosion.
