论文摘要
在这项工作中，我们通过分析地获得了对Nariai时空的高维概括的重力扰动的准光谱，该光谱由二维de安位空间的直接产物组成，并带有几个两个球体。为了获得此结果的关键步骤是根据需要描述的紧张自由度的等级来为角函数使用合适的基础。在这里，我们定义了这样的基础，该基础是张量球形谐波的概括，该量子适用于恒定曲率的几个空间的乘积。
In this work we analytically obtain the quasinormal spectrum for the gravitational perturbation on a higher-dimensional generalization of the Nariai spacetime that is comprised of the direct product of the two-dimensional de Sitter space with several two-spheres. A key step in order to attain this result is to use a suitable basis for the angular functions depending on the rank of the tensorial degree of freedom that one needs to describe. Here we define such a basis, which is a generalization of the tensor spherical harmonics that is suited for spaces that are the product of several spaces of constant curvature.
