Abstract
By generalizing the Holstein-Primakoff realization and the Dyson realization of the Lie algebra SU(2), various realizations of the deformed angular momentum algebra \( \mathcal{R}_{q,s}^{c_0 ,c_1 ,c_2 } \), a five-parameter deformed SU(2) by combining Witten’s two deformation schemes, are investigated in terms of the single boson and the single inversion boson respectively. For each kind, the unitary realization, the non-unitary realization, and their connection by the corresponding similarity transformation are respectively discussed.
