  The inhomogeneous single-, two- and three-boson realizations of the more
general polynomial angular momentum algebra SU_n(2) are obtained from the Fock
representations of SU_n(2) that corresponds to the indecomposable
representation on the space of universal enveloping algebra U(SU_n(2)) and to
the induced representations on the quotient spaces U(SU_n(2))/I_i, with I_i
being some left ideals of U(SU_n(2)).
