Strong Cosmic Censorship for a Scalar Field in a Logarithmic-de Sitter Black Hole

Understand

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-Nordstrom-de Sitter (RNdS) black holes and Born-Infeld-de Sitter (BI-dS) black holes have been discussed.
• In this paper, we investigate SCC in an asymptotic RN-dS black hole with logarithmic nonlinear electromagnetic field perturbed by massless scalar fields.
• It has been argued that SCC can be violated in a near-extremal RN-dS black hole.
