摘要:

在近极值Reissner-Nordstrom-deSitter黑洞中,标量场可以破坏强宇宙审查(SCC).本文研究了带电荷和不带电荷的标量扰动场对Born-Infeld-de Sitter黑洞的强宇宙审查.当Born-Infeld参数b变小时,非线性电动力学效应开始发挥重要作用,并趋于挽救SCC。具体来说,我们发现SCC违规区域的大小随着b的减小而减小。此外,对于一个足够小的b,SCC总是可以恢复在一个近极值Born-Infeld-deSitter黑洞与一个固定的电荷比。

英文摘要:

It has been shown that the Strong Cosmic Censorship (SCC) can be violated by a scalar field in a near-extremal Reissner-Nordstrom-de Sitter black hole. In this paper, we investigate the Strong Cosmic Censorship in a Born-Infeld-de Sitter black hole by a scalar perturbation field with/without a charge. When the Born-Infeld parameter b becomes small, the nonlinear electrodynamics effect starts to play an important role and tends to rescue SCC. Specifically, we find that the SCC violation region decreases in size with decreasing b. Moreover, for a sufficiently small b, SCC can always be restored in a near-extremal Born-Infeld-de Sitter black hole with a fixed charge ratio.
