Multiple Scale and Singular Perturbation Methods

Detailed Summary of the Book

In this book, Kevorkian and Cole delve into multiple scale methods and singular perturbation techniques, two key areas in mathematical analysis often employed to tackle problems characterized by multiple time or space scales. Beginning with an introduction to perturbation theory, this work lays the groundwork for bridging the gap between approximations and exact solutions. Each chapter systematically builds on the theory, illustrating concepts using practical examples from physics, engineering, and beyond.

Readers are introduced to the multiple scale method, a mathematical technique used to develop asymptotic solutions for problems that display distinct behaviors at different scales. The authors explore this framework thoroughly, applying it to classical problems such as vibrations, fluid mechanics, and wave propagation. Singular perturbation theory is another critical focus, where small parameter approximations enable the solution of problems with boundary layers, stiff dynamics, or rapid transient behaviors.

The exposition is not limited to theory. The authors demonstrate the application of these methods through topics such as boundary value problems, matched asymptotic expansions, and nonlinear differential equations. Practitioners gain invaluable insights into how these tools can reveal underlying structures within complex systems, allowing for accurate predictions and better understanding of dynamic behaviors.
