*讲座内容简介：
In this talk, we consider natural Hamiltonians associated with 3 dimensional conformally flat spaces, where the kinetic energies possess 2, 3 and 4 dimensional isometry algebras and the potential functions are added in the presence of symmetry. Separable potentials in the 3 dimensional space reduce to 3 or 4 parameter potentials for Darboux-Koenigs Hamiltonians. Other 3D coordinate systems reveal connections between Darboux-Koenigs and other well known super-integrable Hamiltonians, such as the Kepler problem and isotropic oscillator.
