Plotting any of the coordinates of an integrable system would show that they are quasi-periodic.
An integrable dynamical system will have constants of motion in addition to the energy.
Verdier later worked on the theory of integrable systems.
If , this is the case of a completely integrable Hamiltonian system.
His research is on integrable systems, gauge theory and random matrices.
In general, an integrable system has constants of motion other than the energy.
In mathematics and physics, there are various distinct notions that are referred to under the name of integrable systems.
They are an important tool in soliton theory and integrable systems.
For integrable systems, one has the conservation of the action variables.
He went on to treat problems related both with algebraic geometry and integrable systems.
