Abstract

We study the effects of the null energy condition on totally umbilic hypersurfaces in a class of static spacetimes, both in the spacelike and the timelike case, respectively. In the spacelike case, we study totally umbilic warped product graphs and give a full characterization of embedded surfaces with constant spacetime mean curvature using an Alexandrov Theorem by Brendle and Borghini–Fogagnolo–Pinamonti. In the timelike case, we achieve a characterization of photon surfaces with constant umbilicity factor similar to a result by Cederbaum–Galloway.

论一类静态空间中完全脐状超曲面的空能条件效应

我们分别在类静态时空中和类时空中研究了空能条件对全脐超曲面的影响。在类空间情况下，我们研究了全脐翘曲乘积图，并利用布伦德尔和博格尼-福加尼奥洛-皮纳蒙蒂的亚历山德罗夫定理给出了具有恒定时空平均曲率的嵌入表面的完整特征。在类时间情况下，我们对具有恒定本征因子的光子曲面进行了表征，这与塞德鲍姆-加洛韦（Cederbaum-Galloway）的结果类似。

期刊介绍： This journal examines global problems of geometry and analysis as well as the interactions between these fields and their application to problems of theoretical physics. It contributes to an enlargement of the international exchange of research results in the field. The areas covered in Annals of Global Analysis and Geometry include: global analysis, differential geometry, complex manifolds and related results from complex analysis and algebraic geometry, Lie groups, Lie transformation groups and harmonic analysis, variational calculus, applications of differential geometry and global analysis to problems of theoretical physics.
