Asymptotic charges for spin-1 and spin-2 fields at the critical sets of null infinity
Asymptotic charges for spin-1 and spin-2 fields at the critical sets of null infinity
The asymptotic charges of spin-1 and spin-2 fields are studied near spatial infinity. We evaluate the charges at the critical sets where spatial infinity meets null infinity with the aim of finding the relation between the charges at future and past null infinities. To this end, we make use of …
