Intertwining symmetry algebras of quantum superintegrable systems on the hyperboloid
J. A. Calzada, S. Kuru, J. Negro +1
A class of quantum superintegrable Hamiltonians defined on a two-dimensional hyperboloid is considered together with a set of intertwining operators connecting them. It is shown th…

Superintegrable quantum u(3)--systems and higher rank factorizations
J. A. Calzada, J. Negro, M. A. del Olmo
A class of two-dimensional superintegrable systems on a constant curvature surface is considered as the natural generalization of some well known one-dimensional factorized systems…
