Dirac quasinormal modes of a black hole with quintessence-like matter and a deficit solid angle

Using the third-order WKB approximation, we evaluate the quasinormal frequencies of massless Dirac field perturbation around a black hole with quintessence-like matter and a deficit solid angle. We discuss carefully the properties of quasinormal frequencies with the change of quintessential state parameter w q , the deficit solid angle parameter e, the energy density of quintessence-like matter ρ 0, and the total angular momentum number |k| and the overtone number n, respectively.
