Motion on constant curvature surfaces and a quantization
of some position dependent mass systems
Classical motion on constant curvature surfaces will be analysed and in particular the harmonic oscillator-like system in two dimensions will
be proved to be superintegrable. A quantization of these systems will be
carried out in several alternative ways. This is a report of results of several papers coworked with M.F. Rañada and M. Santander.
