Problem: Dyson-Maleev Representation

  In the Dyson-Maleev representation the spin operators are expressed by the boson creation and annihilation operators tex2html_wrap_inline6313 and a as

  eqnarray2033

where S is the magnitude of the spin. Show that the operators satisfy the spin commutation relations.
