Idea

What is called Liouville integrability is one formalization of the notion of classical integrable system in physics.

A physical system is called Liouville integrable if it admits canonical coordinates and canonical momenta which are generated from the flow of a maximal set of commuting Hamiltonians.

Definition

A physical system given by a phase space symplectic manifold (X,ω)(X, \omega) and equipped with a Hamiltonian H 0C (C)H_0 \in C^\infty(C) (generating time evolution) is said to be Liouville integrable or to be an integrable system in the sens of Liouville if
