文摘A mechanical system whose motion or a physical system whose state is described by the Birkhoff equations is called Birkhoff system. The Birkhoff system is more general than the Hamilton system and has a series of important properties. Therefore, the study of the Birkhoff system becomes a direction of modem developments for mathematical physics science, especially for analytical dynamics.
