In this work, we establish a model of holographic dark energy interacting with dark matter in flat Friedmann-Lemaitre-Robertson-Walker (FLRW) universe and test this model with observational data of Type-Ia supernovae (SNeIa), baryon acoustic oscillation (BAO), cosmic microwave background (CMB) anisotropy and Hubble parameter \(H(z)\). Next we obtain the deceleration parameter and the coincidence parameter and solve the coincidence problem.

一种与暗物质和观测约束相互作用的全息暗能量

在这项工作中,我们建立了全息暗能量模型与平弗里德曼-勒梅特-罗伯逊-沃克(FLRW)宇宙暗物质的相互作用,并测试这一模型与I型的观测数据一个超新星(南京工程公司),重子声学振荡(BAO),宇宙微波背景(CMB)各向异性和哈勃参数\(H(z)\)。接下来,我们获得减速参数和重合参数,并解决重合问题。
