我们证明了质量矢量（Proca）场方程在任意维数的一般Kerr-NUT-AdS黑洞时空中的可分性，填补了文献中长期存在的空白。对得到的四维克尔几何分离方程进行了详细的研究，并计算了相应的拟正态模态。Proca场的三个独立极化中有两个出现在分离分析中，结果与最近的数值研究结果非常吻合，其中完全耦合的偏微分方程在没有使用可分性的情况下处理。
We demonstrate the separability of the massive vector (Proca) field equation in general Kerr-NUT-AdS black-hole spacetimes in any number of dimensions, filling a long-standing gap in the literature. The obtained separated equations are studied in more detail for the four-dimensional Kerr geometry and the corresponding quasinormal modes are calculated. Two of the three independent polarizations of the Proca field are shown to emerge from the separation ansatz and the results are found in an excellent agreement with those of the recent numerical study where the full coupled partial differential equations were tackled without using the separability property.
