论文摘要
众所周知，螺母解决方案具有许多有趣的特征和病理，例如非单星和封闭的时间曲线。事实证明，在较高的尺寸上，地平线拓扑不能是球形的，而是必须是$ 2 $ -spheres的产物，以保持时空的径向对称性。在这封信中，我们希望提出一种新的纯高斯河网$λ$ -VACUUM方程的新解决方案，描述了带有螺母充电的黑洞。它有三个有趣的案例：（a）具有事件和宇宙学视野的黑洞，奇异性隐藏在前者后面，（b）常规时空没有地平线和奇异性，以及（c）带有事件范围的黑洞，没有奇异性和宇宙学地平线。这里的奇异性在$ r \ neq 0 $始终不为中心。
It is known that NUT solution has many interesting features and pathologies like being non-singular and having closed timelike curves. It turns out that in higher dimensions horizon topology cannot be spherical but it has instead to be product of $2$-spheres so as to retain radial symmetry of spacetime. In this letter we wish to present a new solution of pure Gauss-Bonnet $Λ$-vacuum equation describing a black hole with NUT charge. It has three interesting cases: (a) black hole with both event and cosmological horizons with singularity being hidden behind the former, (b) a regular spacetime free of both horizon and singularity, and (c) black hole with event horizon without singularity and cosmological horizon. Singularity here is always non-centric at $r \neq 0$.
