In mathematics, a superintegrable Hamiltonian system is a Hamiltonian system on a 2''n''-dimensional symplectic manifold for which the following conditions hold: (i) There exist ''n'' ≤ ''k'' independent integrals ''F'' ''i'' of motion. Their level surfaces (invariant submanifolds) form a fibered manifold over a connected open subset . (ii) There exist smooth real functions on such that the Poisson bracket of integrals of motion reads . (iii) The matrix function is of constant corank on . If , this is the case of a completely integrable Hamiltonian system. The Mishchenko-Fomenko theorem for superintegrable Hamiltonian systems generalizes the Liouville-Arnold theorem on action-angle coordinates of completely integrable Hamiltonian system as follows. Let invariant submanifolds of a superintegrable Hamiltonian system be connected compact and mutually diffeomorphic. Then the fibered manifold is a fiber bundle in tori . Given its fiber , there exists an open neighbourhood of which is a trivial fiber bundle provided with the bundle (generalized action-angle) coordinates , , such that are coordinates on . These coordinates are the Darboux coordinates on a symplectic manifold . A Hamiltonian of a superintegrable system depends only on the action variables which are the Casimir functions of the coinduced Poisson structure on . The Liouville-Arnold theorem for completely integrable systems and the Mishchenko-Fomenko theorem for the superintegrable ones are generalized to the case of non-compact invariant submanifolds. They are diffeomorphic to a toroidal cylinder . == See also == *Integrable system *Action-angle coordinates 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Superintegrable Hamiltonian system」の詳細全文を読む スポンサード リンク
