This article is devoted to exploring the Rényi holographic dark energy model in the theory of Chern-Simons modified gravity. We studied the deceleration parameter, equation of state, and cosmological plane considering the Amended FRW modal. Modified field equations of -gravity theory gave two independent solutions. In the first case, this model provided the transitional change from deceleration to acceleration compatible with collected observational data. However, it supported a decelerating phase of expansion only in the second case. It was noted that the Equation of State advocated the dominance era under the influence of dark energy in the first case and the second predicted the influence of CDM. In both cases, voted that the universe is in a freezing region and its cosmic expansion is more rapidly accelerated in the background of Chern-Simons modified gravity.

修正 FRW 指标和 Rényi 暗能量模型

本文致力于探索陈-西蒙斯修正引力理论中的Rényi全息暗能量模型。我们研究了考虑修正 FRW 模态的减速参数、状态方程和宇宙学平面。引力理论的修正场方程给出了两个独立的解。在第一种情况下，该模型提供了与收集的观测数据兼容的从减速到加速的过渡变化。然而，它仅在第二种情况下支持扩张的减速阶段。注意到状态方程在第一种情况下主张暗能量影响下的主导时代，第二种情况预测了CDM的影响。在这两种情况下， 投票认为宇宙处于冰冻区域，在陈-西蒙斯修正引力的背景下，宇宙膨胀加速得更快。
