标题： Wormholes with Ends of the World

摘要： 我们研究在包含宇宙末日(EOW)膜、锥形缺陷、折角和穿孔的3D引力中的经典虫洞解。 这些解计算与从二维共形bootstrap中提取的OPE数据的通用渐近行为相关的边界共形场论(BCFT)系综的统计平均值。 锥形缺陷连接BCFT体算符；膜将具有相同边界条件的BCFT边界区间连接起来；折角（沿膜的一维缺陷）连接BCFT边界算符；而穿孔（零维缺陷）是锥形缺陷终止于膜上的端点。 我们提供了引力理论与系综之间对应关系的证据。 特别是，$g$-函数依赖性的吻合来自于在壳EOW膜作用量的底层拓扑特性，由此也得出BCFT版本的Schlenker-Witten定理。 显示英文摘要

摘要： We study classical wormhole solutions in 3D gravity with end-of-the-world (EOW) branes, conical defects, kinks, and punctures. These solutions compute statistical averages of an ensemble of boundary conformal field theories (BCFTs) related to universal asymptotics of OPE data extracted from the 2D conformal bootstrap. Conical defects connect BCFT bulk operators; branes join BCFT boundary intervals with identical boundary conditions; kinks (1D defects along branes) link BCFT boundary operators; and punctures (0D defects) are endpoints where conical defects terminate on branes. We provide evidence for a correspondence between the gravity theory and the ensemble. In particular, the agreement of the $g$-function dependence results from an underlying topological aspect of the on-shell EOW brane action, from which a BCFT analogue of the Schlenker-Witten theorem also follows.
