5-D Einstein-Gauss-Bonnet引力的一些有挠精确解

Some exact solutions with torsion in 5-D Einstein-Gauss-Bonnet gravity

F. Canfora, A. Giacomini, S. Willison

摘要:

导出了Einstein-Gauss-Bonnet引力中有挠量的精确解。这些解具有两个常曲率流形的叉积结构。运动方程给出了理论的耦合常数的关系,以便有非平凡扭转的解决方案。这种关系不是陈-西蒙斯组合。其中一个解具有$AdS_2\times S^3$结构,因此是伯托蒂-罗宾逊时空的纯引力模拟,其中挠率可以看作是协变常数电磁场的对偶。

英文摘要:

Exact solutions with torsion in Einstein-Gauss-Bonnet gravity are derived. These solutions have a cross product structure of two constant curvature manifolds. The equations of motion give a relation for the coupling constants of the theory in order to have solutions with nontrivial torsion. This relation is not the Chern-Simons combination. One of the solutions has a $AdS_2\times S^3$ structure and is so the purely gravitational analogue of the Bertotti-Robinson space-time where the torsion can be seen as the dual of the covariantly constant electromagnetic field.
