旋转对称黎曼流形正质量定理的稳定性

Stability of the Positive Mass Theorem for Rotationally Symmetric Riemannian Manifolds

Dan A. Lee, Christina Sormani

摘要:

利用内禀平坦距离研究了正质量定理的稳定性。特别地,我们考虑了一类具有非负数量曲率且没有内部闭极小曲面的完备渐近平坦旋转对称黎曼流形,其边界要么是最外极小超曲面,要么是空的.我们证明了一列ADM质量收敛于零的流形在点内禀平坦意义下一定收敛于欧几里得空间。实际上,我们通过构造一个显式的填充流形并估计其体积,给出了流形中的环形区域与欧几里得空间中的环形区域之间的内禀平坦距离的显式界.此外,我们包括各种命题,可用于估计的内在平坦的距离之间的黎曼流形没有旋转对称。关于正质量定理在一般情况下的内在平坦稳定性的猜想在最后一节中提出。

英文摘要:

We study the stability of the Positive Mass Theorem using the Intrinsic Flat Distance. In particular we consider the class of complete asymptotically flat rotationally symmetric Riemannian manifolds with nonnegative scalar curvature and no interior closed minimal surfaces whose boundaries are either outermost minimal hypersurfaces or are empty. We prove that a sequence of these manifolds whose ADM masses converge to zero must converge to Euclidean space in the pointed Intrinsic Flat sense. In fact we provide explicit bounds on the Intrinsic Flat Distance between annular regions in the manifold and annular regions in Euclidean space by constructing an explicit filling manifold and estimating its volume. In addition, we include a variety of propositions that can be used to estimate the Intrinsic Flat distance between Riemannian manifolds without rotationally symmetry. Conjectures regarding the Intrinsic Flat stability of the Positive Mass Theorem in the general case are proposed in the final section.
