The vacuum conservation theorem
arXiv:1406.5915 · doi:10.1007/s10714-015-1878-4
Abstract
A version of the vacuum conservation theorem is proved which does not assume the existence of a time function nor demands stronger properties than the dominant energy condition. However, it is shown that a stronger stable version plays a role in the study of compact Cauchy horizons.
