论文摘要
宇宙黑暗部门的奇怪行为为我们提供了通过不同方法来解决宇宙问题的灵活性。使用这种灵活性,我们将黑暗扇区组件之间的能量交换视为可行的候选模型。在目前的工作中,我们研究了两个组分性手性宇宙学的概括中两个标量场之间的相互作用。我们还表明,在相互作用的黑暗扇区模型的字段和流体描述之间存在独特的等效性。后来,使用对动力学系统的定性分析方法进行了对黑色能量销售模型模型的动力学的详细分析。此外,通过对各种宇宙参数的自主系统的相位空间研究,分析了该模型的宇宙学生存力,以指数形式的潜力。
The strange behaviour of the universe's dark sector offers us the flexibility to address cosmological problems with different approaches. Using this flexibility, we consider a possible exchange of energy among the dark sector components as a viable candidate model. In the present work, we investigate the interaction between two scalar fields within the generalization of a two-component chiral cosmology. We also show that there exists a unique equivalence between fields and fluids description of interacting dark sector model. Later, a detailed analysis of the dynamics of the dark energy-dark matter model with coupling in both kinetic and potential parts has been performed using a method of qualitative analysis of dynamical systems. Moreover, the cosmological viability of this model is analyzed for the potential of an exponential form via the phase-space study of autonomous system for various cosmological parameters.
