论文摘要

相应地,我们讨论了一些感兴趣的案例,对单个宇宙学模型中全息暗能量方法和物质创造效应的考虑。我们针对最近的观察测试了这一宇宙论的建议。考虑到自由宇宙学参数获得的最佳拟合值,该模型表现出从减速的宇宙扩张到加速的过渡。减速加速过渡不能从这种模型的巧合参数始终如一地确定。在有效级别上,与整个能量密度贡献相关的参数状态描述了目前流体类比中的精髓情况。

The consideration of the holographic dark energy approach and matter creation effects in a single cosmological model is carried out in this work accordingly, we discuss some cases of interest. We test this cosmological proposal against recent observations. Considering the best fit values obtained for the free cosmological parameters, the model exhibits a transition from a decelerated cosmic expansion to an accelerated one. The deceleration-acceleration transition can not be determined consistently from the coincidence parameter for this kind of model. At effective level the parameter state associated to the whole energy density contribution describes a quintessence scenario in the fluid analogy at present time.
