Geometric Singular Perturbation Theory Beyond the Standard Form (Frontiers in Applied Dynamical Systems: Reviews and Tutorials)

Detailed Summary of the Book

Geometric Singular Perturbation Theory Beyond the Standard Form focuses on expanding the foundational ideas of GSPT to contexts and systems that do not naturally fit into the "standard form" framework. Often, singular perturbation problems in applied mathematics are tackled using systems in standard form—a convenient and straightforward representation. However, real-world challenges, especially in engineering, biology, and physics, demand methods and tools that can deal with systems lying outside this paradigm.

This book systematically covers the underlying theory, mathematical rigor, and computational tools necessary to handle such generalizations. Starting with the historical development and significance of singular perturbation theory, it provides an accessible overview of GSPT while peeling away layer after layer of complexity as the chapters progress. Each chapter builds on the last, moving through advanced topics like folded singularities, canard orbits, loss of normal hyperbolicity, and their implications in applied problems.

A unique aspect of this book is its focus on geometric approaches to systems of ordinary differential equations, as well as a powerful look at delayed Hopf bifurcations, mixed-mode oscillations, and bursting dynamics. By choosing geometric methods as the core analytical tool, this book elegantly connects abstract theory with visualizable, tangible outcomes—a feature highly beneficial in understanding complex dynamical behavior.

Famous Quotes from the Book

"The power of singular perturbation frameworks lies not in their simplicity, but in their adaptability to describe and untangle real complexity."

"While standard-form systems serve as educational cornerstones, the true challenge in modern applications is to envision dynamics where such assumptions no longer apply."

Why This Book Matters
