Universal symmetry Lie algebras for classical two-dimensional Hamiltonians and their translation to quantum mechanics

Universal symmetry algebras are derived for classical two-dimensional Hamiltonians H with the angular momentum M as an integral of motion, by first determining the variables T, Φ,canonically conjugate to H, M. Translation to quantum mechanics cannot be done universally, but is restricted to Hamiltonians with accidental degeneracy. © 1991.SCOPUS: ar.j
