Conserved quantities in general relativity -- the view from null infinity
Po-Ning Chen, Mu-Tao Wang, Ye-Kai Wang +1
In general relativity, an idealized distant observer is situated at future null infinity where light rays emitted from the source approach. This article concerns conserved quantiti…
Supertranslation invariance of angular momentum at null infinity in double null gauge
Po-Ning Chen, Mu-Tao Wang, Ye-Kai Wang +1
The supertranslation invariance of the Chen-Wang-Yau (CWY) angular momentum in the Bondi-Sachs formalism/gauge was ascertained by the authors in \cite{CKWWY_evol, CWWY_atmp}. In th…
A note on the convex body isoperimetric conjecture in the plane
Bo-Hshiung Wang, Ye-Kai Wang
The convex body isoperimetric conjecture in the plane asserts that the least perimeter to enclose given area inside a unit disk is greater than inside any other convex set of area…
Evolution of angular momentum and center of mass at null infinity
Po-Ning Chen, Jordan Keller, Mu-Tao Wang +2
We study how conserved quantities such as angular momentum and center of mass evolve with respect to the retarded time at null infinity, which is described in terms of a Bondi-Sach…
Supertranslation invariance of angular momentum
Po-Ning Chen, Mu-Tao Wang, Ye-Kai Wang +1
LIGO's successful detection of gravitational waves has revitalized the theoretical understanding of the angular momentum carried away by gravitational radiation. An infinite dimens…
Quasi-local mass on unit spheres at spatial infinity
Po-Ning Chen, Mu-Tao Wang, Ye-Kai Wang +1
In this note, we compute the limit of the Wang-Yau quasi-local mass on unit spheres at spatial infinity of an asymptotically flat initial data set. Similar to the small sphere limi…
