论文摘要
在整个研究中一些流行的球形对称常规黑洞的大地测量的整个研究中，我们在此证明了分析性扩展的海沃德黑洞在大地上是不完整的。 Culetu-Simpson-visser非分析光滑黑洞的最简单扩展在地球上也是不完整的，除了径向测量学的抗死式延续外。但是，非分析空间扩展的巨大歧义是大地测量不完整的刺激，除非至少所有扩展都完成了，否则这种空间不能解决奇异性问题。因此，我们提供了这种空间的几种修改，以使它们在超过r = 0的所有可能的扩展中在所有可能的扩展中完成。
Throughout the study of the geodesics of some popular spherically symmetric regular black holes, we hereby prove that the analytically extended Hayward black hole is geodetically incomplete. The simplest extension of the Culetu-Simpson-Visser's non-analytic smooth black hole is also geodetically incomplete, with the exception of the antipodal continuation of the radial geodesics. However, the huge ambiguity in the extension of non analytic spacetimes is tantamount of geodesic incompleteness and such spacetimes do not solve the singularity issue unless at least all the extensions turn out to be complete. Hence, we provide several mere modifications of such spacetimes in order to make them geodetically complete in all possible extensions beyond r=0.
