论文摘要
抗DE保姆（ADS）重力中拓扑翻新的方法在于使动作添加了拓扑术语，该拓扑术语使其有限，同时定义了一个良好的变异问题。在这里，我们使用此处方来解决渐近局部反DE保姆（ALADS）空间的热力学，重点关注Taub-Nut-Ads和Taub-Bolt-Ads-Ads Ads Solutions的Misner弦的物理特性。我们通过在相同的基础上对广告和Alads扇区进行处理来计算Misner弦对熵的贡献。由于发现拓扑翻新可以正确说明该理论的平等性领域的物理量，然后我们研究了添加Chern-Pontryagin拓扑不变的全息后果。特别是，我们讨论了边界应力张量中奇偶校验贡献的出现。
The method of topological renormalization in anti-de Sitter (AdS) gravity consists in adding to the action a topological term which renders it finite, defining at the same time a well-posed variational problem. Here, we use this prescription to work out the thermodynamics of asymptotically locally anti-de Sitter (AlAdS) spacetimes, focusing on the physical properties of the Misner strings of both the Taub-NUT-AdS and Taub-Bolt-AdS solutions. We compute the contribution of the Misner string to the entropy by treating on the same footing the AdS and AlAdS sectors. As topological renormalization is found to correctly account for the physical quantities in the parity preserving sector of the theory, we then investigate the holographic consequences of adding also the Chern-Pontryagin topological invariant to the bulk action; in particular, we discuss the emergence of the parity-odd contribution in the boundary stress tensor.
