In this paper, we considered the Tsallis holographic dark energy model in frames of Nojiri–Odintsov gravity with . For IR, cutoff event horizon is taken. The cosmological evolution of such universe is investigated for various initial conditions and values of parameters. The dependence of the Hubble parameter from time in the future has an oscillation. It is shown that for appearance of singularities are typical and the time up to these singularities can be relatively small from cosmological viewpoint. The singularity is associated with the zero of second derivative of on . It is interesting to note that these models can describe observational data from Ia supernovae astrophysics and dependence of the Hubble parameter from redshift at least not worse than canonical CDM model.

Tsallis 全息暗能量模型,在修正引力下具有事件视界截止
在本文中,我们考虑了 Nojiri-Odintsov 引力框架中的 Tsallis 全息暗能量模型. 对于 IR,采用截止事件视界。对这种宇宙的宇宙演化进行了各种初始条件和参数值的研究。哈勃参数的依赖性从未来的时间开始有一个振荡。结果表明,对于奇点的出现是典型的,从宇宙学的角度来看,到达这些奇点的时间可能相对较小。奇点与二阶导数的零点有关上. 有趣的是,这些模型可以描述来自 Ia 超新星天体物理学的观测数据以及哈勃参数对红移的依赖性至少不比规范差清洁发展机制模型。
