论文摘要
这项研究调查了高维单一旋转的迈尔斯 - 珀里·德·保姆（MP-DS）黑洞对标量场扰动的稳定性。讨论了带有一个自旋参数的MP-DS黑洞的相位空间。此外，MP-DS黑洞的准模式（QNM）是通过渐近迭代方法和六阶温ZEL-KRAMER-BRILLOUIN近似近似计算的。对于近超级MP-DS黑洞，事件范围可能很近。在这种情况下，Pöschl-Teller技术可为QNM提供准确的分析公式。发现当黑洞的自旋参数增加时，标量扰动模式在较高的频率下振荡并更快地衰减。此外，发现具有单个旋转的MP-DS黑洞在扰动下是稳定的。
This study investigates the stability of higher-dimensional singly rotating Myers-Perry-de Sitter (MP-dS) black holes against scalar field perturbations. The phase spaces of MP-dS black holes with one spin parameter are discussed. Additionally, the quasinormal modes (QNMs) of MP-dS black holes are calculated via the asymptotic iteration method and sixth-order Wentzel-Kramers-Brillouin approximation. For near-extremal MP-dS black holes, the event horizon may be considerably close to the cosmological horizon. In such cases, the Pöschl-Teller technique yields an accurate analytic formula for the QNMs. It is found that when the spin parameter of a black hole increases, the scalar perturbation modes oscillate at higher frequencies and decay faster. Furthermore, the MP-dS black hole with a single rotation is found to be stable under perturbation.
