Brown-York Energy in Spacetimes with Horizon
arXiv:2101.00493 · doi:10.1103/PhysRevD.103.026002
Abstract
We obtain a simple relationship between the change in the Brown-York energy inside of a closed two-surface just outside of a horizon of spacetime, and the change in the area of that two-surface.
