Angular momentum of isolated systems in general relativity
Adam Helfer
TL;DR
This paper discusses the treatment of angular momentum in radiating systems within general relativity, addressing the supertranslation problem to clarify how angular momentum is defined and conserved in such contexts.
Contribution
It provides an accessible explanation of the angular momentum problem in general relativity, focusing on the supertranslation issue for non-specialists.
Findings
