利用Regge和Wheeler提出的方法,导出了广义Schwarzschild几何的轴扰动方程.对给定角动量L和λ参数,通过数值计算,得到了拟正则模的值.数值结果与不稳定性的解析证明相一致.Using Regge-Wheeler's method,axial perturbation equation of generalized Schwarzschild geometry is derived.The numerical results of quasi-normal modes for given angular momentum L and parameter λ indicate the instability of the geometry,which is in agreement with our analytic results.
