论文摘要
我们研究了一个具有共构耦合标量张量理论的高阶，并具有与高斯 - 骨网标量相关的协变量几何约束。这是一种特殊的Horndeski理论，包括规范的动力学术语，但对于标量而没有变化或平等对称性。该理论还源于kaluza-klein的降低，对较高的维度度量理论的定义良好。分析了渐近平面的球形对称黑洞的性能，并发现新的旋转和辐射扩展。通过静态构型的异常转换，提出了引力的单极样溶液和永恒的虫洞。后者证明可以从时空提取可能的裸奇异点，从而产生完全规则且渐近平坦的空间。
We study a higher order conformally coupled scalar tensor theory endowed with a covariant geometric constraint relating the scalar curvature with the Gauss-Bonnet scalar. It is a particular Horndeski theory including a canonical kinetic term but without shift or parity symmetry for the scalar. The theory also stems from a Kaluza-Klein reduction of a well defined higher dimensional metric theory. Properties of an asymptotically flat spherically symmetric black hole are analyzed, and new slowly rotating and radiating extensions are found. Through disformal transformations of the static configurations, gravitating monopole-like solutions and eternal wormholes are presented. The latter are shown to extract from spacetime possible naked singularities, yielding completely regular and asymptotically flat spacetimes.
