Dynamical Symmetry of the Zwanziger problem in Non-commutative Quantum   Mechanics
  The non-relativistic hydrogen atom and the Zwanziger problem have the same dynamical symmetry for bound and scattering states.We show that this is also true for a Hilbert space which is non-commutative in co-ordinates. The group structure is described using the redefined velocity operator and Laplace Runge-Lenz operator in terms of left and right handed representations of the non-commutative Hilbert space $ R_{\lambda}^{3}$.The bound state algebra is SO(4) and the scattering state algebra is SO(3,1).
