Theory and Methods. Wiley, Chiches|er, 1991, 509 pp.,
It is the premise of this book that even at a beginning level, perturbation theory should be presented not as an isolated collection of cookbook techniques but as a part of the mainstream of mathematics. This means that theorems covered in other mathematics courses will be encountered. This book makes such theorems available by a clear statement in an appendix. Throughout the book an effort has boon made to say the important things that no one ever seems to say, the simple insights tbat finally dawn after months, or even years, of working with a method. Contents: Chapter 1: Root Finding Chapter 2: Regular Perturbations Chapter 3: Direct Error Estimation Chapter 4: Periodic Solutions and Lindstedt Series Chapter 5: Multiple Scales Chapter 6: Averaging Chapter 7: Initial Layers Chapter 8: Boundary Layers Chapter 9: Methods of the WKB Type Appendices Symbol Index Index. This book is in many ways complementary to Nayfeh's books, and certainly does not replace them. Preliminary drafts have been used in courses. The book may well become the foundation of a senior-graduate student course in perturbations. (WFA)
