The objective of the present paper is to investigate an almost-pseudo-Ricci symmetric FRW spacetime with a constant Ricci scalar in a dynamic cosmological term $\Lambda \left(t\right)$ and equation of state (EoS) $\omega \left(t\right)$ scenario. Several cosmological parameters are calculated in this setting and thoroughly studied, which shows that the model satisfies the late-time accelerating expansion of the universe. We also examine all of the energy conditions to check our model’s self-stability.

具有动态宇宙项和状态方程的几乎伪 Ricci 对称 FRW 宇宙

本文的目的是在动态宇宙学术语中研究具有恒定 Ricci 标量的几乎伪 Ricci 对称 FRW 时空 $\Lambda \left(吨\right)$ 和状态方程 (EoS) $\omega \left(吨\right)$设想。在此设置下计算并深入研究了几个宇宙学参数，表明该模型满足宇宙后期加速膨胀。我们还检查了所有能量条件以检查我们模型的自稳定性。
