论文摘要
我们研究了移位对称动力学重力编织中的隐形黑洞扰动，并获得了奇数甚至奇偶校区的类似的regge-wheeler和Zerilli Master方程。我们表明，静态和球形对称隐形黑洞的非平凡头发仅贡献了平均均值主方程的附加源术语。此外，我们将精确的溶液推导到单极和偶极扰动中，并表明它们通常是病理非尺寸模式，或者将其降低到一般相对性的纯柱低阶多极端。
We study stealth black hole perturbations in shift symmetric kinetic gravity braiding and obtain its analogous Regge-Wheeler and Zerilli master equations for the odd and even parity sectors. We show that the nontrivial hair of static and spherically symmetric stealth black holes contributes only an additional source term to the even parity master equation. Furthermore, we derive exact solutions to the monopolar and dipolar perturbations and show that they are generally pathological non-gauge modes, or else reduce to the pure-gauge low-order multipoles of general relativity.
