本研究证明亚极端Kerr--Newman--de Sitter黑洞的引力电磁扰动具有宇称等谱性,通过辐射规范下的主变量直接重构,无需慢旋转或小电荷近似。
AI 中文摘要
广义相对论中真空Kerr扰动的偶宇称与奇宇称准正则频率相同。我们建立了亚极端Kerr--Newman--de Sitter黑洞线性引力电磁扰动的这种宇称等谱性,无需慢旋转或小电荷展开。我们直接在辐射规范下从规范不变主变量重构辐射度规和规范势扰动,无需中间复势。
英文摘要
Vacuum Kerr perturbations in general relativity have identical even- and odd-parity quasinormal frequencies. We establish this parity isospectrality for linear gravitoelectromagnetic perturbations of subextremal Kerr--Newman--de Sitter black holes, without a slow-rotation or small-charge expansion. We reconstruct the radiative metric and gauge-potential perturbations directly from gauge-invariant master variables in radiation gauge, without an intermediate complex potential.
