This invaluable book examines qualitative and quantitative methods for nonlinear differential equations, as well as integrability and nonintegrability theory. S

This book is devoted to the relation between two different concepts of integrability: the complete integrability of complex analytical Hamiltonian systems and t

This distinctive volume presents a clear, rigorous grounding in modern nonlinear integrable dynamics theory and applications in mathematical physics, and an int

This is the first book to systematically state the fundamental theory of integrability and its development of ordinary differential equations with emphasis on t

Symmetries and singularity structures play important roles in the study of nonlinear dynamical systems. It was Sophus Lie who originally stressed the importance
