It has been shown that the Christodoulou version of the strong cosmic censorship (SCC) conjecture can be violated for a scalar field in a near-extremal Reissner-Nordstrom-de Sitter black hole. In this paper, we investigate the effects of higher derivative corrections to the Einstein-Hilbert action on the validity of SCC, by considering a neutral massless scalar perturbation in - and -dimensional Einstein-Maxwell-Gauss-Bonnet-de Sitter black holes. Our numerical results show that the higher derivative term plays a different role in the case than it does in the case. For , the SCC violation region increases as the strength of the higher derivative term increases. For , the SCC violation region first increases and then decreases as the higher derivative correction becomes stronger, and SCC can always be restored for a black hole with a fixed charge ratio when the higher derivative correction is strong enough. Finally, we find that the version of SCC is respected in the case, but can be violated in some near-extremal regimes in the case.

对 Einstein-Maxwell-Gauss-Bonnet-de Sitter 黑洞中标量场的强大宇宙审查这项工作部分得到 NSFC (11005016、11875196、11375121) 的支持
已经表明,对于近极值 Reissner-Nordstrom-de Sitter 黑洞中的标量场,强宇宙审查 (SCC) 猜想的 Christodoulou 版本可能会被违反。在本文中,我们通过考虑- 和 -维 Einstein-Maxwell-Gauss-Bonnet-de Sitter 黑洞中的中性无质量标量扰动来研究对 Einstein-Hilbert 作用的更高导数校正对 SCC 有效性的影响。我们的数值结果表明,较高导数项在案例中的作用与在案例中的作用不同。对于,SCC 违反区域随着高阶导数项的强度增加而增加。为了,随着高导校正变强,SCC破坏区先增大后减小,当高导校正足够强时,对于固定电荷比的黑洞,SCC总是可以恢复的。最后,我们发现SCC 的版本在本案中得到尊重,但在本案中的一些接近极端的制度下可能会被违反。
