This book is a revised and updated version including a substantial portion ofnew material of the authors widely acclaimed earlier text PerturbationMethods in Applied Mathematics. A new chapter dealing with regular expansionshas been added the discussion of layertype singular perturbations has beenrevised and the coverage of multiple scale and averaging methods has beensignificantly expanded to reflect recent advances and viewpoints. The result isa comprehensive account of the various perturbation techniques currently usedin the sciences and engineering and is suitable for a graduate text as well asa reference work on the subject. «
