Classical Soft Graviton Theorem to Memory Effect and Violation of Peeling

Abstract

It has been known for some time that the asymptotic structure of spacetime and soft theorems are closely related. To study the structure of future null infinity, studying the classical soft graviton theorem is often quite helpful. The memory effect at the future null infinity can be demonstrated from the leading behavior of gravitational radiation low-frequency. However, the memory effect is not the only information we can get from soft gravitational radiation. This paper demonstrates how the classical soft graviton theorem enlightens us about the memory effect and the differential structure of the future null infinity.
