Multi-Hamiltonian Theory of Dynamical Systems

This is a modern approach to Hamiltonian systems where multi-Hamiltonian systems are presented in book form for the first time. These systems allow a unified treatment of finite, lattice and field systems. Having more than one Hamiltonian formulation in a single coordinate system for a nonlinear system is a property closely related to integrability. Thus, the book presents an algebraic theory of integrable systems. It is written for scientists and graduate students.

Klappentext

This book offers a modern introduction to the Hamiltonian theory of dynamical systems, presenting a unified treatment of all types of dynamical systems, i.e., finite, lattice, and field. Particular attention is paid to nonlinear systems that have more than one Hamiltonian formulation in a single coordinate system. As this property is closely related to integrability, this book presents an algebraic theory of integrable.
