Dirac Quasinormal Modes of the Schwarzschild--anti-de Sitter Black Hole with a Global Monopole

The quasinormal modes associated with the decay of Dirac field perturbation around a Schwarzschild-anti-de Sitter black hole with a global monopole (SAdSBHGM) are calculated using the Horowitz--Hubeny approach. For the large SAdSBHGM, we find that η has little effect on the quasinormal frequencies. However, for the intermediate and small SAdSBHGM, in the limit η→1/√8π, the real parts of the fundamental quasinormal frequencies approximate the linear functions of T, and the imaginary ones approximate the linear functions of r₊.
