In mathematics, a superintegrable Hamiltonian system is a Hamiltonian system on a 2n-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 $F : Z \to N = F (Z)$ over a connected open subset $N \subset ℝ^{k}$ .

(ii) There exist smooth real functions $s_{i j}$ on $N$ such that the Poisson bracket of integrals of motion reads ${F_{i}, F_{j}} = s_{i j} \circ F$ .

(iii) The matrix function $s_{i j}$ is of constant corank $m = 2 n - k$ on $N$ .

If $k = n$ , 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 $F$ is a fiber bundle in tori $T^{m}$ . Given its fiber $M$ , there exists an open neighbourhood $U$ of $M$ which is a trivial fiber bundle provided with the bundle (generalized action-angle) coordinates $(I_{A}, p_{i}, q^{i}, ϕ^{A})$ , $A = 1, \dots, m$ , $i = 1, \dots, n - m$ such that $(ϕ^{A})$ are coordinates on $T^{m}$ . These coordinates are the Darboux coordinates on a symplectic manifold $U$ . A Hamiltonian of a superintegrable system depends only on the action variables $I_{A}$ which are the Casimir functions of the coinduced Poisson structure on $F (U)$ .

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 $T^{m - r} \times ℝ^{r}$ .
