The Quasi-exact models in two-dimensional curved space based on the   generalized CRS Harmonic Oscillator
  In this paper, by searching the relation between the radial part of Higgs harmonic oscillator in the two-dimensional curved space and the generalized CRS harmonic oscillator model, we can find a series of quasi-exact models in two-dimensional curved space based on this relation.
