F(R)引力与爱因斯坦共形不变Maxwell源的关系

The relation between F(R) gravity and Einstein-conformally invariant Maxwell source

S. H. Hendi

摘要:

本文考虑了$F(R)$引力的特殊情况,其中$F(R)= R^{N}$是一个拓扑的黑洞解,并得到了它在高维空间的拓扑黑洞解.我们证明,与高维带电黑洞一样,只要适当地选取解的参数,这些解可以解释为具有两个事件视界、极端黑洞和裸奇点的黑洞解.但是,所得到的黑洞与标准的高维Reissner-Nordstrom解不同.其次,我们将重点放在共形不变的麦克斯韦场耦合到爱因斯坦引力,并讨论其黑洞解。通过对这两类解的比较,发现在任意维情况下,Einstein共形不变Maxwell解与无物质场的$F(R)$引力解之间存在着对应关系.

英文摘要:

In this paper, we consider the special case of $F(R)$ gravity, in which $F(R)= R^{N}$ and obtain its topological black hole solutions in higher dimensions. We show that, the same as higher dimensional charged black hole, these solutions may be interpreted as black hole solutions with two event horizons, extreme black hole and naked singularity provided the parameters of the solutions are chosen suitably. But, the presented black hole is different from the standard higher-dimensional Reissner-Nordstrom solutions. Next, we focus on the conformally invariant Maxwell field coupled to Einstein gravity and discuss about its black hole solutions. Comparing these two class of solutions, shows that there is a correspondence between the Einstein-conformally invariant Maxwell solutions and the solutions of $F(R)$ gravity without matter field in arbitrary dimensions.
