在本文中,我们表明,渐近迭代法(AIM)允许一个数值上找到Schwarzschild和Schwarzschild de Sitter黑洞的拟正规模式。该方法的另一个好处是,它也可以用来计算自旋为零扰动情况下的史瓦西反德西特准正规模。我们还讨论了一个改进的版本的AIM,更适合于数值实现。
In this paper we show that the asymptotic iteration method (AIM) allows one to numerically find the quasinormal modes of Schwarzschild and Schwarzschild de Sitter black holes. An added benefit of the method is that it can also be used to calculate the Schwarzschild anti-de Sitter quasinormal modes for the case of spin-zero perturbations. We also discuss an improved version of the AIM, more suitable for numerical implementation.
