Strong cosmic censorship for charged de Sitter black holes with a charged scalar field
arXiv:1808.04832 · doi:10.1088/1361-6382/aafcf2
Abstract
It has been shown recently that the strong cosmic censorship conjecture is violated by near-extremal Reissner-Nordström-de Sitter black holes. We investigate whether the introduction of a charged scalar field can rescue strong cosmic censorship. We find that such a field improves the situation but there is always a neighbourhood of extremality in which strong cosmic censorship is violated by perturbations arising from smooth initial data.
