论文摘要
在本文中，我们应用了全息原理，以统一的方式描述早期和后期的宇宙，当时一般的状态方程包含庞大的粘度。我们使用Nojiri和Odintsov（2006,2017）引入的广义全息暗能量的想法，并在国家方程有两个幂律渐近线时研究宇宙的演变。从粒子范围内获得了红外临界值的分析表达式。从全息视角得出的能源保护定律是针对各种形式的热力学参数和各种形式的大量粘度赋予的。结果，我们在存在粘性全息流体的情况下获得了早期和晚期宇宙的统一描述。
In this article we apply the holographic principle for describing in a unifying way the early and the late-time universe, when the general equation of state contains a bulk viscosity. We use the idea of a generalized cut-off holographic dark energy introduced by Nojiri and Odintsov (2006,2017), and study the evolution of the universe when the equation of state has two power-law asymptotes. Analytical expressions for the infrared cut-offs in terms of the particle horizon are obtained. The energy conservation laws as derived from the holographic point of view, are given for various forms of the thermodynamic parameters and for various forms of the bulk viscosity. As a result, we obtain a unifying description of the early and the late-time universe in the presence of a viscous holographic fluid.
