Ruban的带电尘埃溶液--与Reissner-Nordström和壳层穿越的匹配

The charged dust solution of Ruban -- matching to Reissner--Nordström and shell crossings

Andrzej Krasiński, Gabriel Giono

摘要:

具有$e^2 < m^2$的最大扩展的Reissner-Nordström(RN)流形要求附加一个物质源,以保持渐近平坦区域的无限链并通过RN奇点之间的虫洞演化。到目前为止,这些尝试令人沮丧。在这里,我们尝试一个更可能的来源-一个解决方案,发现鲁班在1972年,这是一个收费的概括不均匀的Kantowski-萨克斯型尘埃解决方案。它可以与RN解匹配,并且匹配表面必须始终保持在两个RN事件视界之间。然而,壳交叉不允许最大和最小尺寸之间的振荡的半个周期。

英文摘要:

The maximally extended Reissner--Nordström (RN) manifold with $e^2 < m^2$ begs for attaching a material source to it that would preserve the infinite chain of asymptotically flat regions and evolve through the wormhole between the RN singularities. So far, the attempts were discouraging. Here we try one more possible source -- a solution found by Ruban in 1972 that is a charged generalisation of an inhomogeneous Kantowski--Sachs-type dust solution. It can be matched to the RN solution, and the matching surface must stay all the time between the two RN event horizons. However, shell crossings do not allow even half a cycle of oscillation between the maximal and the minimal size.
