这封信是对先前 f(R) 引力理论中引力波 (GW) 结果的概括。在之前的一些论文中，特定的 f(R) 理论在文献中首次被线性化。现在，这个过程被进一步推广，表明每个 f(R) 理论都可以线性化，产生第三种大规模的引力辐射模式。在此框架中，以前的结果是本信中讨论的更普遍问题的特殊情况。还通过纵向响应函数的辅助讨论了 LISA 对此类巨大引力波的潜在可检测性。
This Letter is a generalization of previous results on gravitational waves (GWs) from f(R) theories of gravity. In some previous papers, particular f(R) theories have been linearized for the first time in the literature. Now, the process is further generalized, showing that every f(R) theory can be linearized producting a third massive mode of gravitational radiation. In this framework, previous results are particular cases of the more general problem that is discussed in this Letter. The potential detectability of such massive GWs with LISA is also discussed with the auxilium of longitudinal response functions.
