RT Journal Article T1 Haantjes Structures for the Jacobi-Calogero Model and the Benenti Systems. A1 Tondo, Giorgio A1 Tempesta, Piergiulio AB In the context of the theory of symplectic-Haantjes manifolds, we construct the Haantjes structures of generalized Stackel systems and, as a particular case, of the quasi-bi-Hamiltonian systems. As an application, we recover the Haantjes manifolds for the rational Calogero model with three particles and for the Benenti systems.
