From the book reviews: "The book falls into two quite distinct parts, reflecting the expertises of the two authors. The first part gives a detailed and formal description of asymptotic methods, whilst the second part considers a number of fluid mechanics problems. ... There are numerous problems presented at the end of each chapter, which are accompanied by extremely comprehensive solutions ... . this book should prove a useful text for final year undergraduate students and for postgraduate (both taught and research) students wishing to master modern asymptotic methods." (P. W. Duck, Mathematical Reviews, Issue 2008 a) "The novelty of this book lies in the use of thorough and advanced singular perturbation methods in combination with detailed applications to fluid mechanics. ... In the combination of asymptotics and fluid mechanics in such a fundamental and detailed approach, the book is unique in the science literature." (Ferdinand Verhulst, Dynamical Systems Magazine, October, 2007) "Asymptotic Analysis and Boundary Layers is an extended English edition of Analyse asymptotique et couche limite published in the Springer series Mathematique et Applications. The book presents a new method of asymptotic analysis of boundary layer problems, the successive Complementary Expansion Method (SCEM). ... With its chapter summaries, detailed derivations of results, discussed examples and fully worked out problems and solutions, the book is selfcontained. It is accessible to graduate and postgraduate students of engineering and physics with a good knowledge in fluid mechanics." (Francisco Perez Acosta, Zentralblatt MATH, Vol. 1115 (17), 2007)
