BMS charges without supertranslation ambiguity
Po-Ning Chen, Mu-Tao Wang, Ye-Kai Wang +1
The asymptotic symmetry of an isolated gravitating system, or the Bondi-Metzner-Sachs (BMS) group, contains an infinite-dimensional subgroup of supertranslations. Despite decades o…
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…
