论文摘要
在本文中，我们研究了r $ \急性{e} $ nyi全息暗能量（RHDE）模型，在各向同性和空间均质的平面flrw（Friedmann-Lema $ \ hat I $ tre-Robertson-walker）宇宙的框架中，通过考虑不同的量子$Δ$ nif cot take $ nif niffrr，friedmannlemannllema $ \ hat i $ tre-tre-robertson-walker）的范围。我们通过分析扰动的增长率和状态基层层次结构检查了RHDE模型。状态基层次结构的进化轨迹$ s_3^1 $，$ s_3^2 $ $ $ s_4^1 $，$ s_4^2 $对redshift $ z $，在整个宇宙演变中表现出令人满意的行为。探索暗能量模型的有利设备之一是CND（复合零诊断）$ \ {s_3^1 - ε\} $和$ \ {s_4^1 - ε\} $，其中$ \ \ \ \ \ \ \ \ {s_3^1- $^$和$ s_ $和s_ s_ s_ s_ s_ s_ s_ 1-^1-特征和从$λ$ CDM的出发可以得到很多评估。
In this paper, we have examined the R$\acute{e}$nyi holographic dark energy (RHDE) model in the framework of an isotropic and spatially homogeneous flat FLRW (Friedmann- Lema$\hat i$tre-Robertson-Walker) Universe by considering different values of parameter $δ$, where the infrared cut-off is taken care by the Hubble horizon. We examined the RHDE model through the analysis of the growth rate of perturbations and the statefinder hierarchy. The evolutionary trajectories of the statefinder hierarchy $S_3^1$, $S_3^2$ $S_4^1$, $S_4^2$ versus redshift $z$, shows satisfactory behaviour throughout the Universe evolution. One of the favourable appliance for exploring the dark energy models is the CND (composite null diagnostic) $\{ S_3^1 - ε\}$ and $\{ S_4^1 - ε\}$, where the evolutionary trajectories of the $\{ S_3^1 - ε\}$ and $\{ S_4^1 - ε\}$ pair show remarkable characteristics and the departure from $Λ$CDM could be very much assessed.
