The purpose of these lecture notes is to develop a theory of asymptotic expansions for functions involving two variables, while at the same time using functions

Matched Asymptotic Expansions and Singular Perturbations

This outstanding text concentrates on the mathematical ideas underlying various asymptotic methods for ordinary differential equations that lead to full, infini
