We used modified holographic Ricci dark energy to find anisotropic LRS Bianchi type I cosmological model in five-dimensions based on Lyra geometry. The exact solutions of the Einstein field equations were obtained by using hybrid expansion law (HEL). We have investigated the interacting and noninteracting dark energy and dark matter. It is found that at late times the equation of state parameter (EOS) for non-interacting case behaves like a cosmological constant whereas it behaves like phantom dark energy for interacting model. Some cosmological parameters and stability of the models are discussed. The physical and geometric aspects of the models have been analysed. They are consistent with the recent observational results.

Lyra 流形中的高维各向异性修正全息 Ricci 暗能量宇宙模型

我们使用改进的全息 Ricci 暗能量在基于 Lyra 几何的五维中找到各向异性 LRS Bianchi I 型宇宙学模型。爱因斯坦场方程的精确解是通过使用混合膨胀定律(HEL)获得的。我们研究了相互作用和非相互作用的暗能量和暗物质。发现在后期,非相互作用情况下的状态参数方程 (EOS) 表现得像一个宇宙常数,而它表现得像相互作用模型的幻影暗能量。讨论了模型的一些宇宙学参数和稳定性。已经分析了模型的物理和几何方面。它们与最近的观察结果一致。
