麦克斯韦试验场和克尔外部的线性化重力解都存在非辐射模式，即非平凡的与时间无关的解。这些都与守恒电荷密切相关。在这篇文章中，我们讨论了线性化引力的非辐射模，它可以被看作是对应于Poincarélie代数的。Kerr的二维等距群对应于一个规范不变的两参数非辐射模族，它表示质量和方位角动量的无限微小扰动。我们用线性化的Newman-Penrose标量来计算线性化的质量电荷。
Maxwell test fields as well as solutions of linearized gravity on the Kerr exterior admit non-radiating modes i.e. non-trivial time-independent solutions. These are closely related to conserved charges. In this paper we discuss the non-radiating modes for linearized gravity which may be seen to correspond to the Poincaré Lie algebra. The two-dimensional isometry group of Kerr corresponds to a two-parameter family of gauge-invariant non-radiating modes representing infinitesimal perturbations of mass and azimuthal angular momentum. We calculate the linearized mass charge in terms of linearized Newman–Penrose scalars.
