Multiseparability and Superintegrability for Classical and Q(20)

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

One can transfer this Schrodinger equation with a scalar potential Vn to one with vector potential n through the use of a multiplier transformation . Setting (x)= (x) (x) for a nonzero scalar function we nd

In the paper 17] and the book 18] all separable coordinates for the equation are constructed, where n is the Laplace-Beltrami operator on n= n . It is shown that all separable coordinates are orthogonal and that for S each separable coordinate system the corresponding separated solutions are characterized as simultaneous eigenfunctions of a set of n second order commuting symmetry operators for n. Moreover, the equation ( n+Vn)= where the scalar potential takes the form
