近视界引力荷

Near horizon gravitational charges

Hai-Shan Liu, Pujian Mao

摘要:

本文研究了Newman-Penrose形式中的近视界对称性和引力荷。特别是,我们调查的效果从拓扑条款。我们发现庞特里亚金项和高斯-邦纳项对近视界电荷有重要的影响,并带来了有趣的新特征。我们证明了由庞特里亚金项和高斯-邦纳项等拓扑项导出的引力荷可以由辛势的模糊性得到。

英文摘要:

In this paper, we study the near horizon symmetry and gravitational charges in the Newman-Penrose formalism. In particular we investigate the effect from topological terms. We find that the Pontryagin term and Gauss-Bonnet term have significant influence on the near horizon charges and bring interesting novel features. We show that the gravitational charge derived from a general class of topological terms including the Pontryagin term and Gauss-Bonnet term can be obtained from the ambiguities of the symplectic potential.
