高维Lovelock和$AdS_5$ Chern-Simons引力的精确解

Exact Solutions in Higher-Dimensional Lovelock and $AdS_5$ Chern-Simons Gravity

Francesco Bajardi, Daniele Vernieri, Salvatore Capozziello

摘要:

采用Cartan结构方程,研究了$D$维时空中的Lovelock引力。在这种背景下,我们找到了宇宙学和球对称背景下的精确解。在后一种情况下,我们还得到了视界和相应的贝肯斯坦-霍金熵。此外,我们专注于拓扑Chern-Simons理论,提供在5维的精确解。具体地说,它是可能的,表明反德西特不变陈-西蒙斯重力可以在5维Lovelock-Zumino重力框架内,为特定的选择Lovelock参数。

英文摘要:

Lovelock gravity in $D$-dimensional space-times is considered adopting Cartan's structure equations. In this context, we find out exact solutions in cosmological and spherically symmetric backgrounds. In the latter case, we also derive horizons and the corresponding Bekenstein--Hawking entropies. Moreover, we focus on the topological Chern--Simons theory, providing exact solutions in 5 dimensions. Specifically, it is possible to show that Anti-de Sitter invariant Chern--Simons gravity can be framed within Lovelock--Zumino gravity in 5 dimensions, for particular choices of Lovelock parameters.
