Separability theory of Gel'fand-Zakharevich systems on Riemannian manifolds
Abstract:
A complete separability theory of Liouville integrable systems with
n quadratic in momenta constants of motion is presented. It is geometric
separability theory of Gel'fand-Zakharevich bi-Hamiltonian systems on Riemannian
manifolds. We start with the separability of systems generated by the so-called
special conformal Killing tensors, i.e. Benenti systems. Then, infinitely
many new classes of separable systems are constructed by appropriate deformations
of Benenti class systems. All such systems can be lifted to the Gel'fand-Zakharevich
bi-Hamiltonian form.
