Nonlinear *sl(2)* algebras subtending generalized angular momentum theories are studied in terms of undeformed generators and bases. We construct their unitary irreducible representations in such a general context. The linear *sl(2)*-case as well as its *q*-deformation are easily recovered as specific examples. Two other physically interesting applications corresponding to the... Show more
