论文摘要
我们表明，在洛夫洛克重力中可能存在渐近的de de保姆黑洞。这样的黑洞具有非恒定曲率的地平线几何形状，被称为异国黑孔。我们明确检查了高斯 - 骨网的情况。我们简要讨论了正质量案例，其中我们展示了横向空间几何形状如何影响黑洞是否存在。对于负质量解决方案，我们显示了如何根据横向空间的几何形状来显示三个不同的黑洞空位。我们还为几何参数提供了封闭形式的表达式，以确保观察到黑洞时空。我们讨论了无数案件的讨论，那里有许多不同的空间允许。
We show that asymptotically de Sitter black holes of negative mass can exist in Lovelock gravity. Such black holes have horizon geometries with non-constant curvature and are known as Exotic Black Holes. We explicitly examine the case of Gauss-Bonnet gravity. We briefly discuss the positive mass case where we show how the transverse space geometry affects whether a black hole will exist or not.For negative mass solutions we shown how three different black hole spacetimes are possible depending on the transverse space geometry. We also provide closed form expressions for the geometric parameters to ensure that a black hole spacetime is observed. We close with a discussion of the massless case, where there are many different spacetimes that are permitted.
