Query: Algebraic approach to exact solution of the (2 + 1)-dimensional Dirac
  oscillator in the noncommutative phase space   In this paper we study the (2 + 1)-dimensional Dirac oscillator in the
noncommutative phase space and the energy eigenvalues and the corresponding
wave functions of the system are obtained through the sl(2) algebraization. It
is shown that the results are in good agreement with those obtained previously
via a different method.
