摘要
在最近的论文中，Fuentealba、Henneaux和Troessaert (FHT) 提出了在ADM哈密顿正式化下定义超平移不变Lorentz电荷的定义，并展示了这些定义在虽然静止无穷远处的Chen、Wang和Yau (CWY) 定义的Lorentz电荷中与之匹配，这些定义不含“超平移歧义”。在本简短注释中，受FHT分析的启发，我们在Beig-Schmidt变量中给出时空与时类无穷远处的超平移不变Lorentz电荷的表达式。我们 presenting calculations, building upon the work of Comp\`ere, Gralla, and Wei (CGW), to show that our expressions for supertranslation invariant Lorentz charges match the CWY definitions at null infinity.
