Asymptotic Perturbation Theory Of Waves

This book is an introduction to the perturbation theory for linear and nonlinear waves in dispersive and dissipative media.\n\nThe main focus is on the direct asymptotic method which is based on the asymptotic expansion of the solution in series of one or more small parameters and demanding finiteness of the perturbations; this results in slow variation of the main-order solution. The method, which does not depend on integrability of basic equations, is applied to quasi-harmonic and non-harmonic periodic waves, as well as to localized waves such as solitons, kinks, and autowaves. The basic theoretical ideas are illustrated by many physical examples throughout the book.Asymptotic Perturbation Theory Of Waves is written by Lev Ostrovsky and published by ICP.
