根据Singh和Joshi给出的结果,指出初始密度和速度分布对决定球形尘埃崩塌的最终结果的作用,本文从视界演化的角度考察了奇点的因果结构。我们还提出了一些有助于理解这一奇点的性质的相关特征,包括测地线族的行为以及与奇点稳定性有关的一些方面。
Further to results given by Singh and Joshi, pointing out the role of initial density and velocity distributions towards determining the final outcome of spherical dust collapse, the causal structure of a singularity is examined here in terms of evolution of the apparent horizon. We also bring out several related features which help towards understanding the nature of this singularity, including the behaviour of geodesic families and some aspects related to the stability of the singularity.
