Lecture Notes on Asymptotic Analysis

By Tiejun Li

The aim of this course is to teach the students the basic asymptotic analysis techniques. Only the asymptotic analysis for ODEs are discussed since it is aimed to second year undergrad students. The students are assumed to have the basic knowledge about the ODEs and complex analysis.
