Classification of the classicalSL(2,R)gauge transformations in the rigid body

Abstract: In this paper we revisit the classification of the gauge transformations in the Euler top system using the generalized classical Hamiltonian dynamics of Nambu. In this framework the Euler equations of motion are bi-Hamiltonian and SL(2, R) linear combinations of the two Hamiltonians leave the equations of motion invariant, although belonging to inequivalent Lie-Poisson structures. Here we give the explicit form of the Hamiltonian vector fields associated to the components of the angular momentum for every sing… Show more

“…In this latter case the Casimir surface can also have the geometry of an elliptic cone or a hyperbolic cylinder in the proper limit situations. A complete classification of the geometrical shapes of the Casimir surface C 1 can be found in [37]. Regarding the solutions of the Euler equations (12), given the ordering (10) of the dimensionless inertia parameters, the solutions depend of the relative value between e 0 and e 2 .…”
