内容説明
Numerical Hamiltonian Problems presents a unified introduction to the interdisciplinary and growing field of symplectic integration of Hamiltoian problems. The authors explain in detail how to derive, analyze, and use symplectic integrators and report virtually all available symplectic methods using a coherent notation. The book requires very little background knowledge. It.provides numerical examples throughout and includes five chapters on Hamiltonian problems and numerical methods.
