论文摘要
我们考虑了Einstein-Gauss-Bonnet重力{\ it} Kaluza-Klein路线的较低维度限制的动作原理。我们研究真空并获得一些精确的解决方案。我们发现，这些理论的现实状况可以从通常在爱因斯坦 - 高斯 - 邦纳特重力中出现的两个真空中选择一个真空。我们获得了带有标质头发的精确黑洞和宇宙学解决方案，包括标量毛状BTZ黑洞，质量和角动量开启。我们还讨论了渐近广告背景中的全息中心电荷。
We consider the action principles that are the lower dimensional limits of the Einstein-Gauss-Bonnet gravity {\it via} the Kaluza-Klein route. We study the vacua and obtain some exact solutions. We find that the reality condition of the theories may select one vacuum over the other from the two vacua that typically arise in Einstein-Gauss-Bonnet gravity. We obtain exact black hole and cosmological solutions carrying scalar hair, including scalar hairy BTZ black holes with both mass and angular momentum turned on. We also discuss the holographic central charges in the asymptotic AdS backgrounds.
