论文摘要

我们证明,空中式球形对称常数平均曲率(SSCMC)表面和一般的间距类似常数均值曲率(CMC)表面具有某些边界状态,在未来的schwarzschild spacetime中未来的无界限是wang \ cite {wang2001} and chrich的意义上是渐进的副周期。 \ cite {chruscielherzlich}。接近未来的零污染度($ s = 0 $),我们得出的是,可以将空格型CMC表面的边界数据表示为$ \ m athbb {s}^{2} $上的三个订单,并获得第四阶衍生物接近$ s = 0 $的兼容性条件。我们还表明,如果第二个基本形式的无跟踪部分$ \ MATHING足够快地将此空间型CMC表面衰减快速降低,则限制其副函数$ p $(有关定义,请参见Null-Infinity上的\ eqref {defofp}),必须是$ \ null-Infinction in Null-Infinity of null-Infinity of null-Infinity的eigenfunction null-Infinction null-infinction null-infinction null-infinction null-infinction null-Infinction n laplace on laplace。尤其是在Minkowski时空中,证明了$ s = 0 $的独特结果和空间般的CMC表面的构造。另外,我们表明某些空间类CMC表面的内部边界完全是大地测量的。

We prove that a spacelike spherical symmetric constant mean curvature (SSCMC) surface and a general spacelike constant mean curvature (CMC) surface with certain boundary condition at the future null-infinity in Schwarzschild spacetime are asymptotically hyperbolic in the sense of Wang \cite{Wang2001} and Chruściel-Herzlich \cite{ChruscielHerzlich} respectively. Near the future null-infinity ($s=0$), we derive that the boundary data of spacelike CMC surfaces can be expressed as those on $\mathbb{S}^{2}$ up to three order and obtain a compatibility condition for fourth order derivatives near $s=0$. We also show that if the trace free part of the second fundamental forms $\mathring A$ of this spacelike CMC surface decay fast enough then the restriction of its associate function $P$ (for definition, see \eqref{defofp} ) on the null-infinity must be a first eigenfunction of the Laplace on $\mathbb{S}^2$ or constant. In particular in Minkowski spacetime, a uniqueness result and constructions of spacelike CMC surfaces near $s=0$ are proved. Also, we show that the inner boundary of certain spacelike CMC surfaces are totally geodesic.
