论文摘要
强大的宇宙审查制度的命运最终与cauchy地平线的扰动的扩展性有关，并已知在带电的DE Sitter Black Hole的近极端地区被侵犯。在较高的曲率理论中也可以实现类似的违规行为，与一般相对论相比，违规的强度变得更强大。在这项工作中，我们进一步扩展了这项分析，以研究在规范化的四维爱因斯坦高斯 - 邦网理论相对于标量和电磁扰动的情况下，强宇宙审查猜想的有效性。我们还研究标量场的晚期尾巴。
The fate of strong cosmic censorship is ultimately linked to the extendibility of perturbation across the Cauchy Horizon and known to be violated in the near extremal region of a charged de Sitter black hole. Similar violations can also be realized in higher curvature theories, with the strength of violation becoming stronger as compared to general relativity. In this work, we extend this analysis further to study the validity of strong cosmic censorship conjecture in the context of the regularised four-dimensional Einstein Gauss-Bonnet theory with respect to both scalar and electromagnetic perturbation. We also study the late time tails of scalar fields.
