Rényi holographic dark energy (RHDE) correspondence is discussed in higher dimensional cosmology, namely Kaluza-Klein (KK) cosmology. Both interacting and non-interacting cosmological scenario are considered here. It is found that the non-interacting model naturally leads to the late accelerated universe, unlike the standard Holographic Dark Energy models in 4D, which requires interaction to accommodate the late-time acceleration of the universe. The interacting model produces an accelerating universe at late time albeit failing to attain the estimated present value of the deceleration parameter. The evolution of different cosmologically relevant parameters have been estimated. We consider here two diagnostic tests namely, state-finder and Om diagnostics to study the non-interacting model which is more favoured in the light of recent cosmological observations. Classical stability of the cosmological models are also discussed

高维宇宙学中的人一全息暗能量

Rényi 全息暗能量 (RHDE) 对应在更高维宇宙学中讨论,即 Kaluza-Klein (KK) 宇宙学。这里考虑了相互作用和非相互作用的宇宙学场景。发现非交互模型自然会导致晚期加速宇宙,这与4D中的标准全息暗能量模型不同,后者需要交互以适应宇宙晚期加速。尽管未能达到减速参数的估计现值,但相互作用模型在后期产生了加速宇宙。已经估计了不同的宇宙学相关参数的演化。我们在这里考虑两种诊断测试,即 state-finder 和 Om 诊断来研究根据最近的宇宙学观察更受青睐的非相互作用模型。还讨论了宇宙学模型的经典稳定性
