我们使用Tattersall，拉各斯和Ferreira [Phys. Rev. D 96，064011（2017）]提出的协变公式来分析不同引力理论家族中球对称背景下线性扰动的结构，从而研究扰动黑洞的准正规模式如何受到广义相对论修正的影响。我们限制自己的单张量，标量张量和矢量张量同态不变的引力模型在史瓦西黑洞的背景。我们明确地显示了完整的协变形式的二次行动在这种情况下，这使我们能够分析奇奇偶校验（轴向）和偶奇偶校验（极）扰动同时在一个简单的方式。
We use the covariant formulation proposed by Tattersall, Lagos, and Ferreira [Phys. Rev. D 96, 064011 (2017)] to analyze the structure of linear perturbations about a spherically symmetric background in different families of gravity theories, and hence study how quasinormal modes of perturbed black holes may be affected by modifications to general relativity. We restrict ourselves to single-tensor, scalar-tensor and vector-tensor diffeomorphism-invariant gravity models in a Schwarzschild black hole background. We show explicitly the full covariant form of the quadratic actions in such cases, which allow us to then analyze odd parity (axial) and even parity (polar) perturbations simultaneously in a straightforward manner.
