Superintegrability of the Post-Winternitz system on spherical and hyperbolic spaces

Abstract

The properties of the Tremblay-Turbiner-Winternitz system (related to the harmonic oscillator) were recently studied on the two-dimensional spherical $S_{\kappa }^2$ ($\kappa >0$) and hiperbolic $H_{\kappa }^2$ ($\kappa <0$) spaces (J. Phys. A : Math. Theor. 47, 165203, 2014). In particular, it was proved the higher-order superintegrability of the TTW system by making use of (i) a curvature-dependent formalism, and (ii) existence of a complex factorization for the additional constant of motion. Now a similar study is presented for the Post-Winternitz system (related to the Kepler problem). The curvature $\kappa$ is considered as a parameter and all the results are formulated in explicit dependence of $\kappa$. This technique leads to a correct definition of the Post-Winternitz (PW) system on spaces with curvature $\kappa$, to a proof of the existence of higher-order superintegrability (in both cases, $\kappa >0$ and $\kappa <0$), and to the explicit expression of the constants of motion.
