A tensorial approach to the theory of classical Hamiltonian integrable systems is proposed, based on the geometry of Haantjes tensors. We introduce the class of symplectic-Haantjes manifolds (or manifolds), as a natural setting where the notion of integrability can be formulated. We prove that the existe…
