Asymptotic Schwarzschild Spacetimes

Abstract

It is shown that if an asymptotically flat spacetime is asymptotically stationary, in the sense that $\Lie_ξ g_{ab}$ vanishes at the rate $\sim t^{-3}$ for asymptotically timelike vector field $ξ^a$, and the energy-momentum tensor vanishes at the rate $\sim t^{-4}$, then the spacetime is an asymptotically Schwarzschild spacetime. This gives a new aspect of the uniqueness theorem of a black hole.
