论文摘要
在\ cite {compere：2019odm}中提出了无限的引力记忆塔，通过考虑物质引起的真空过渡的冲动极限。我们可以替代纽曼 - 普埃罗斯形式主义中无限塔的引力记忆。我们还证明，每个顺序的记忆都可以与相同的超级翻译相关联，而不是超级译本或超级反抗的无限塔。
An infinite tower of gravitational memories was proposed in \cite{Compere:2019odm} by considering the matter-induced vacuum transition in the impulsive limit. We give an alternative realization of the infinite towers of gravitational memories in Newman-Penrose formalism. We also demonstrate that the memories at each order can be associated to the same supertranslation instead of infinite towers of supertranslations or superrotations.
