Query: Exact solutions of a two-dimensional Kemmer oscillator in the
  gravitational field of cosmic string   The two dimensional Kemmer oscillator under the influence of the
gravitational field produced by a topology such as the cosmic string spacetime
and in the presence of a uniform magnetic field as well as without magnetic
field are investigated.
