SUq,h(cross) to 0(2) and SUq,h(cross)(2), the classical and quantum q-deformations of the SU(2) algebra. III. When q is a root of unity

Abstract
For pt.II see ibid., vol.23, p.5371 (1990). The q-oscillator of type one and the classical and the quantum q-deformations of SU(2) algebra realized through the q-oscillators are studied in the case of q being roots of unity, i.e. qk=1. The q-excitations are found to be non-bosonic. In particular, when k is of rank 4 and 6, the q-excitations are shown to be fermionic and parafermionic respectively.
