Strong Cosmic Censorship for a Scalar Field in a Logarithmic-de Sitter Black Hole
Yiqian Chen, Qingyu Gan, Guangzhou Guo
It has been shown that the quasinormal modes of perturebated fields can be used to investigate the validity of strong cosmic censorship (SCC). Relevant issues for Reissner-Nordstro…
