标题： Quasi-normal Modes of near-extremal black holes in Generalized spherically symmetric spacetime and Strong Cosmic Censorship Conjecture

摘要： 利用若干接近极值的条件，可以将广义球对称黑洞背景中的中性纯量扰动的动力学方程简化为具有Pöschl-Teller势的微分方程。 得到了准正频率的一个解析公式。 然后使用该解析公式研究广义黑洞时空在光滑初值条件下强宇宙审查猜想（SCC）的性质。发现Christodoulou版本的SCC在某些黑洞参数空间区域（包括广义相对论中的黑洞）中被违反，而$C^{1}$版本的SCC始终成立。 显示英文摘要

摘要： A number of near-extremal conditions are utilized to simplify the equation of motion of the neutral scalar perturbations in generalized spherically symmetric black hole background into a differential equation with the P\"{o}schl-Teller potential. An analytic formula for quasinormal frequencies is obtained. The analytic formula is then used to investigate Strong Cosmic Censorship conjectures~(SCC) of the generalized black hole spacetime for the smooth initial data. The Christodoulou version of the SCC is found to be violated for certain regions of the black hole parameter space including the black holes in General Relativity while the $C^{1}$ version of the SCC is always valid.
