论文摘要
在本文中，我们研究了Newman-Penrose形式主义中的近地平线对称性和重力电荷。特别是我们从拓扑术语中研究了效果。我们发现，Pontryagin术语和高斯式术语对近地平线的指控具有重大影响，并带来了有趣的新颖特征。我们表明，可以从合成电位的歧义中获得拓扑术语的一般拓扑术语的重力电荷。
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.
