  The effective potential for the axial mode of gravitational wave on
noncommutative Schwarzschild background is presented.
  Noncommutativity is introduced via deformed Hopf algebra of diffeomorphisms
by means of a semi-Killing Drinfeld twist.
  The analysis is performed up to the first order in perturbation of the metric
and noncommutativity parameter.
  This results in a modified Regge-Wheeler potential with the strongest
differences in comparison to the classical Regge-Wheeler potential being near
the horizon.
