高曲率引力中的强宇宙审查

Strong Cosmic Censorship in higher curvature gravity

Akash K Mishra, Sumanta Chakraborty

摘要:

广义相对论的决定论性质是由强宇宙监督猜想所保证的,该猜想断言时空不可能以平方可积联系延伸到柯西视界之外。虽然这个猜想在广义相对论中对渐近平坦的黑洞时空成立,但在带电的渐近德西特时空中可能会违反这个猜想。由于爱因斯坦-希尔伯特作用量预计将涉及更高的曲率修正,在这篇文章中,我们研究了是否可以恢复信心,在强宇宙审查时,更高的曲率修正广义相对论被认为是。与我们的预期相反,我们已经明确表明,不仅违反了猜想发生在极值附近,但违反似乎变得更强的强度较高的曲率项的增加。

英文摘要:

Deterministic nature of general relativity is ensured by the strong cosmic censorship conjecture, which asserts that spacetime cannot be extended beyond Cauchy horizon with square integrable connection. Although this conjecture holds true for asymptotically flat black hole spacetimes in general relativity, a potential violation of this conjecture occurs in charged asymptotically de Sitter spacetimes. Since it is expected that Einstein-Hilbert action will involve higher curvature corrections, in this article we have studied whether one can restore faith in the strong cosmic censorship when higher curvature corrections to general relativity are considered. Contrary to our expectations, we have explicitly demonstrated that not only a violation to the conjecture occurs near extremality, but the violation appears to become stronger as the strength of the higher curvature term increases.
