论文摘要
我们在一组特定的张量 - 星期量表理论中构建了毛茸茸的黑洞解决方案，目标空间接收一个杀戮矢量场，其周期性流动，这是一个单参数的点转换家族的发电机，这使整个理论不变。至于标量相对性的标量头发的黑洞，这些必须是旋转的物体，因为标量源于超级不稳定性。我们分析了五个理论中最基本的旋转解决方案（绕组数量$ m = 1 $），这些理论彼此不同，目标空间的高斯曲率值。研究了这些溶液的存在域，以及它们的毛茸茸，地平线和变形因子。
We construct hairy black hole solutions in a particular set of tensor-multi-scalar theories of gravity for which the target-space admits a Killing vector field with periodic flow that is furthermore the generator of a one-parameter family of point transformations which leave the whole theory invariant. As for black holes with scalar hair in general relativity, these must be rotating objects as the scalarization arises from superradiant instability. We analyze the most fundamental rotating solutions (winding number $m=1$) in five theories which differ from each other by the value of the Gauss curvature of the target-space. The domain of existence of these solutions is investigated, as well as their hairyness, horizon area and deformation factor.
