Multiseparability and Superintegrability for Classical and Q(3)

时间:2025-04-05

Abstract It has long been known that there are potentials on n-dimensional constant curvature spaces for which a given Hamiltonian system in classical mechanics, and Schrodinger equation in quantum mechanics, admits solutions via separation of variables in

and S (q) is the action function, 19]. The quantum analog of this classical system is given by the Schrodinger equation H (q)= E (q) (3) where in local coordinates n 1 X@ (pggjk )@ H= n+ V (q); (4) n=p g j;k@qj@qk=1

and g= det(gjk)? . Recall that a complete integral S (q;;; n) of the Hamilton-Jacobi equation solves the associated classical mechanical system 19, 20]. (A complete integral is a solution of (1) such that locally1 1
