论文摘要
在目前的工作中，我们研究了一个扁平的FRW宇宙中的r $ \急性{e} $ NYI全息暗能模型（RHDE），在该宇宙中，哈勃式的地平线可以通过hubble Horizon进行护理，并通过对黑物质和暗能量之间的相互作用项的三个不同的参数进行护理。通过图形分析，在宇宙进化的过程中，某些宇宙学参数的行为，尤其是减速参数，状态（EOS）参数方程，能量密度参数和声音的平方速度。
In the present work, we study the R$\acute{e}$nyi holographic dark energy model (RHDE) in a flat FRW Universe where the infrared cut-off is taken care by the Hubble horizon and also by taking three different parametrizations of the interaction term between the dark matter and the dark energy. Analyzing graphically, the behavior of some cosmological parameters in particular deceleration parameter, equation of state (EoS) parameter, energy density parameter and squared speed of sound, in the process of the cosmic evolution, is found to be leading towards the late-time accelerated expansion of the RHDE model.
