The Wigner Kernel of a Particle obtained from the Wigner Kernel of a
Spin by Group Theoretical Contraction
Jean-Pierre Amiet, Stefan Weigert
abstract: The Moyal formalism for a particle can be derived from the Moyal formalism
for a spin. This is done by contracting the group of rotations to the
oscillator group. A new derivation is given for the contraction of the spin
Wigner-kernel to the Wigner kernel of a particle.
