Dirac quasi-normal frequencies in a noncommutative black hole space-time

Noncommutative geometry may be an alternative way to quantum gravity. We study the influence of the space-time noncommutative parameter on the Dirac quasi-normal modes in the noncommutative Schwarzschild black hole space-times. In comparison to the commutative Schwarzschild black hole, the numerical results show that the oscillation frequencies and magnitude of the imaginary part of the Dirac quasi-normal modes will increase. However, it is found that the influence of the space-time noncommutative parameter on the Dirac quasi-normal modes is tiny and negligible. (author)
