论文摘要
这项研究的重点是宇宙常数对静态背景下度上对称物质配置的影响。我们扩展了Herrera \ cite {Herrera2021 Hyperloce}的工作，并描述了这种排斥性特征对倍感各向异性流体的一些现实特征的影响。在描述了爱因斯坦 - $λ$运动方程之后，我们详细介绍了相应的质量函数及其保护定律。在我们的研究中，除了观察负能量密度之外，我们还注意到Minkowskian Core的形成，因为物质的内容被迫本身不要跟随对称轴附近的内向运动。在$λ$汤匙时期发现了三个解决方案。首先是通过将零值保持在Weyl标量的情况下计算得出，而第二个解决方案在夸张紧凑对象的随后变化中保持零复杂性。但是，最后一个模型涵盖了自磨削系统内的僵硬流体。这种类型的理论设置表明，它直接链接研究了一些特定的量子场景，其中注意到$λ$占主导地位的能量密度的负面行为。
This study focuses on the impact of the cosmological constant on hyperbolically symmetric matter configurations in static background. We extend the work of Herrera \cite{herrera2021hyperbolically} and describe the influences of such repulsive character on a few realistic features of hyperbolical anisotropic fluids. After describing Einstein-$Λ$ equations of motion, we elaborated the corresponding mass function along with its conservation laws. In our study, besides observing negative energy density, we notice the formation of Minkowskian core as matter content is compelled itself not to follow inward motion near the axis of symmetry. Three families of solution are found in $Λ$-dominated epoch. First is calculated by keeping zero value to Weyl scalar, while the second solution maintains zero complexity in the subsequent changes of the hyperbolical compact object. However, the last model encompasses stiff fluid within the self-gravitating system. Such type of theoretical setup suggests its direct link to study a few particular quantum scenarios where negative behavior of energy density is noticed at $Λ$ dominated regime.
