We prove several rigidity results related to the spacetime positive mass theorem. A key step is to show that certain marginally outer trapped surfaces are weakly outermost. As a special case, our results include a rigidity result for Riemannian manifolds with a lower bound on their scalar curvature.
我们证明了几个与时空正质量定理相关的刚性结果。关键步骤是证明某些临界外捕获面是弱最外层的。作为一个特殊情况,我们的结果包括对标量曲率有下界的黎曼流形的一个刚性结果。
