论文摘要
在本文中，我们利用动力学系统的理论来研究宇宙标准宇宙学模型的动力学，该模型被称为$λ$ CDM模型。我们假设宇宙中的物质含量由不相互相互作用的正压完美液体组成。此外，我们提出了适当的物理解释，以及宇宙的规模扩展因子和宇宙学密度参数之间的新依赖性。
In this paper we exploit the theory of the dynamical systems to study the dynamics of the standard cosmological model of the universe, which is known as the $Λ$CDM model. We assume that the matter content in our universe consists of barotropic perfect fluids without mutual interaction. Furthermore, we present the appropriate physical interpretation, as well as new dependencies between the scale expansion factor of the universe and cosmological density parameters.
