    "abstract": "A deformed boson mapping of the Marumori type is derived for an underlying\n$su(2)$ algebra. As an example, we bosonize a pairing hamiltonian in a two\nlevel space, for which an exact treatment is possible. Comparisons are then\nmade between the exact result, our q- deformed boson expansion and the usual\nnon - deformed expansion.",
