These lecture notes provide a fresh approach to investigating singularly perturbed systems using asymptotic and geometrical techniques. It gives many examples and step-by-step techniques, which will help beginners move to a more advanced level.
Singularly perturbed systems appear naturally in the modelling of many processes that are characterized by slow and fast motions simultaneously, for example, in fluid dynamics and nonlinear mechanics. This book’s approach consists in separating out the slow motions of the system under investigation. The result is a reduced differential system of lesser order. However, it inherits the essential elements of the qualitative behaviour of the original system.
Singular Perturbations differs from other literature on the subject due to its methods and wide range of applications. It is a valuable reference for specialists in the areas of applied mathematics, engineering, physics, biology, as well as advanced undergraduates for the earlier parts of the book, and graduate students for the later chapters.
“Biochemical or physical models’ dimensions can often be reduced by taking into account the order of magnitude of the processes they describe. This book gives many examples of such a reduction being performed by applying the mathematical theory of singular perturbations. … this book is an excellent introduction to classical singular perturbations, enriched by some new authors’ ideas inspired by control theory … .” (Eric Benoît, Mathematical Reviews, June, 2015)
