In mathematics, a superintegrable Hamiltonian system is a Hamiltonian system on a
-dimensional symplectic manifold for which the following conditions hold: (i) There exist
independent integrals
Their level surfaces (invariant submanifolds) form a fibered manifold
over a connected open subset
(ii) There exist smooth real functions
such that the Poisson bracket of integrals of motion reads
(iii) The matrix function
is of constant corank
, 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
There exists an open neighbourhood
which is a trivial fiber bundle provided with the bundle (generalized action-angle) coordinates
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
