论文摘要
在爱因斯坦重力与非线性电磁场耦合的框架中，我们研究了磁性黑洞的重力 - 电磁扰动。扰动的主方程是通过Chandrasekhar的程序获得的，其中具有奇数的引力扰动与偶数偶数偶联。作为应用程序，我们使用数值方法应用了主方程来获得三种常规黑洞的准模式（QNM）。结果表明，常规黑洞的QNM显着取决于理论的参数和黑洞的磁电荷，并且与Reissner-Nordström黑洞的参数非常不同。这些结果的迹象详细讨论了这些常规黑洞的稳定性。
In the framework of Einstein's gravity coupled to nonlinear electromagnetic fields, we study gravito-electromagnetic perturbations of magnetic regular black holes. The master equations of perturbations are obtained through Chandrasekhar's procedure, in which gravitational perturbations with odd-parity are coupled to the electromagnetic perturbations with even-parity. As an application, we apply the master equations to obtain quasinormal modes (QNMs) for three types of regular black holes by using numerical method. Results show that QNMs of regular black holes depends significantly on the parameters of the theory and the magnetic charge of the black holes and are very different from that of the Reissner-Nordström black hole. Indications of these results on the stability of these regular black holes are discussed in detail.
