Math 6730 - Asymptotic and Perturbation Methods

Time: 2-3:20pm T,TH

Place: JWB 333

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.
