摘要:

我们经常遇到这样的情况:黑洞解可以被视为更简单解的连续变形,或者通过连续参数修改广义相对论。我们开发了一个通用框架,用于计算此类变形问题中准正则模频率的高阶微扰修正。我们的方法具有许多应用,并且能够非常精确地计算高阶修正的数值。对于几个例子,我们明确执行了此计算,并讨论了准正则模频率对于变形参数的解析性质。

英文摘要:

We often encounter a situation that black hole solutions can be regarded as continuous deformations of simpler ones, or modify general relativity by continuous parameters. We develop a general framework to compute high-order perturbative corrections to quasinormal mode frequencies in such deformed problems. Our method has many applications, and allows to compute numerical values of the high-order corrections very accurately. For several examples, we perform this computation explicitly, and discuss analytic properties of the quasinormal mode frequencies for deformation parameters.
