Math 6730 - Asymptotic and Perturbation Methods

Place: LCB 222

Makeup sessions: Oct 8, Oct 22, Dec 3 in LCB 222 3:40-5:00 pm

Course Description:

In this course, we will discuss the 4 basic problems of singular perturbation theory, namely singular boundary value problems, singular initial value problems, multiple time scale problems, and multiple space scale problems. The specific names of the techniques are matched asymptotic expansions, multiple-time scale analysis, averaging, and homogenization. Applications will made to a variety of problems in the physical and life sciences, including fluid dynamics, enzyme kinetics, cardiac electrophysiology, and many more. In addition to covering the theory for these methods and applications, we will make extensive use of Maple to do explicit calculations. A more detailed outline of the course is contained in this .pdf file
