我们证明，当辐射度规和物质扰动由遵循封闭复线性系统且带有复线性边界条件的复主变量重构时，线性无关解之间的黑洞等谱性成立。若相位旋转将一个宇称扇区映射到另一个，则偶宇称和奇宇称QNM（准正态模式）谱重合，扰动为宇称等谱。大量手征对齐理论满足这些准则，作为应用，我们证明亚极端Kerr-de Sitter黑洞是宇称等谱的。
英文摘要
We prove that black-hole isospectrality between linearly independent solutions follows whenever radiative metric and matter perturbations are reconstructed from complex master variables obeying a closed, complex-linear system with complex-linear boundary conditions. If a phase rotation maps one parity sector to the other, then the even- and odd-parity QNM spectra coincide, and the perturbations are parity isospectral. A broad class of chiral-aligned theories satisfies these criteria. As an application, we demonstrate that subextremal Kerr--de Sitter black holes are parity isospectral.
