Query: Noncommutative scalar quasinormal modes and quantization of entropy of a
  BTZ black hole   We obtain an exact analytic expression for the quasinormal modes of a
noncommutative massless scalar field in the background of a massive spinless
BTZ black hole up to the first order in the deformation parameter. We also show
that the equations of motion governing these quasinormal modes are identical in
form to the equations of motion of a commutative massive scalar field in the
background of a fictitious massive spinning BTZ black hole. This results hints
at a duality between the commutative and noncommutative systems in the
background of a BTZ black hole. Using the obtained results for quasinormal mode
frequencies, the area and entropy spectra for the BTZ black hole in the
presence of noncommutativity are calculated. In particular, the separations
between the neighboring values of these spectra are determined and it is found
that they are nonuniform. Therefore, it appears that the noncommutativity leads
to a non-equispaced (discrete) area and entropy spectra.
