Query: A Group-Theoretical Method for Natanzon Potentials in Position-Dependent
  Mass Background   A new manner for deriving the exact potentials is presented. By making use of
conformal mappings, the general expression of the effective potentials deduced
under su(1,1) algebra can be brought back to the general Natanzon
hypergeometric potentials.
