Quasi-local energy from a Minkowski reference
Chiang-Mei Chen, Jian-Liang Liu, James M. Nester
The specification of energy for gravitating systems has been an unsettled issue since Einstein proposed his pseudotensor. It is now understood that energy-momentum is \emph{quasi-l…
Gravitational energy is well defined
Chiang-Mei Chen, Jian-Liang Liu, James M. Nester
The energy of gravitating systems has been an issue since Einstein proposed general relativity: considered to be ill defined, having no proper local density. Energy-momentum is now…
Rigidity of isometric immersions into the light cone
Jian-Liang Liu, Chengjie Yu
In this paper, we show the rigidity of isometric immersions for a Riemannian manifold of dimension into the light cone of dimensional Minkowski, de Sitter and anti-de S…
Quasilocal energy and surface geometry of Kerr spacetime
Chengjie Yu, Jian-Liang Liu
We study the quasi-local energy (QLE) and the surface geometry for Kerr spacetime in the Boyer-Lindquist coordinates without taking the slow rotation approximation. We also conside…
Covariant Hamiltonian boundary term: Reference and quasi-local quantities
Gang Sun, Chiang-Mei Chen, Jian-Liang Liu +1
The Hamiltonian for dynamic geometry generates the evolution of a spatial region along a vector field. It includes a boundary term which determines both the value of the Hamiltonia…
Chen-Nester-Tung quasi-local energy and Wang-Yau quasi-local mass
Jian-Liang Liu, Chengjie Yu
In this paper, we show that the Chen-Nester-Tung (CNT) quasi-local energy is closely related to the Wang-Yau (WY) quasi-local mass. As a particular example, we compute the second v…
