由IMP胶合引起的时空的因果测地线不完备性
Causal geodesic incompleteness of spacetimes arising from IMP gluing
摘要:
2002年,IMP通过胶合构造法构造了一系列真空初始数据集。在本文中,我们调查了这些初始数据集的局部几何以及它们的时空发展的影响。特别是,我们的状态的存在条件的外部被困表面的IMP胶合颈部的中心附近,从而使用一个推广的彭罗斯不完整性定理推导出空的不完整性所产生的时空。
英文摘要:
In 2002, Isenberg-Mazzeo-Pollack (IMP) constructed a series of vacuum initial data sets via a gluing construction. In this paper, we investigate some local geometry of these initial data sets as well as implications regarding their spacetime developments. In particular, we state conditions for the existence of outer trapped surfaces near the center of the IMP gluing neck and thence use a generalization of the Penrose incompleteness theorem to deduce null incompleteness of the resulting spacetimes.
