摘要:

本文推广了高维Lovelock引力中一个产生静态球对称黑洞解的已知定理。特定的极限,如高斯-博内(GB)和/或爱因斯坦-希尔伯特(EH)在任何维度$N$产生所有已知的解决方案,迄今为止的能量动量。在我们的推广中,特别强调了三阶Lovelock引力,我们发现了两类不同的解决方案,其特征在于物质场参数。几个特殊的情况下进行了研究,并讨论了有关的渐近行为的属性。我们的一般解决方案,包括拓扑黑洞,以及自然分裂成不同的类,如陈-西蒙(CS)和博恩-因菲尔德(BI)在更高的维度。研究了裸奇异性的出现,发现当用量子测试粒子探测时,时空表现出量子力学意义下的非奇异性。将该定理推广到仅含GB参数的Bertotti-Robinson(BR)型解.最后,我们还证明了定理的推广更高维的标量张量源$(N>4)$不工作。

英文摘要:

Generalization of a known theorem to generate static, spherically symmetric black-hole solutions in higher dimensional Lovelock gravity is presented. Particular limits, such as Gauss-Bonnet (GB) and/or Einstein-Hilbert (EH) in any dimension $N$ yield all the solutions known to date with an energy-momentum. In our generalization, with special emphasis on the third order Lovelock gravity, we have found two different class of solutions characterized by the matter field parameter. Several particular cases are studied and properties related to asymptotic behaviours are discussed. Our general solution which covers topological black holes as well, splits naturally into distinct classes such as Chern-Simon (CS) and Born-Infeld (BI) in higher dimensions. The occurence of naked singularities are studied and it is found that, the spacetime behaves nonsingular in quantum mechanical sense when it is probed with quantum test particles. The theorem is extended to cover Bertotti-Robinson (BR) type solutions in the presence of the GB parameter alone. Finally we prove also that extension of the theorem for a scalar-tensor source of higher dimensions $(N>4)$ fails to work.
