论文摘要
在本文中，已经构建了一个稳定的扁平宇宙学模型，并在最近建议的$κ（R，T）$ GRAVITY的框架中研究了暗能量的演变。我们在当前工作中采用的经验方法揭示了一些与观测值和标准$λ$ CDM模型一致的有趣的宇宙学特征。宇宙压力的演变显示出与宇宙减速加速过渡相对应的正负跃迁，同时，减速参数和宇宙压力都具有正到阴性的符号翻转。尽管这种行为可以为减速加速过渡提供解释，但这种积极阴性过渡本身背后的原因仍然缺失。
In this paper, a stable flat cosmological model has been constructed and the evolution of dark energy has been investigated in the framework of the recently suggested $κ(R,T)$ gravity. The empirical approach we adopt in the current work reveals some interesting cosmological features consistent with observations and the standard $Λ$CDM model. The evolution of cosmic pressure shows a positive-to-negative transition corresponding to the cosmic deceleration-acceleration transition, both the deceleration parameter and the cosmic pressure have the positive-to-negative sign flipping. While this behavior can provide explanation for the deceleration-acceleration transition, the reason behind this positive-negative transition itself is still missing.
