摘要:

本文考虑了高维时空中三种不同的暗能量模型,并对一些宇宙学参数进行了数值讨论。第一个模型是一个单组分宇宙,包括粘性变化的修改Chaubergin气体。在第二个模型中,我们考虑了包含粘性变化的修正Chaobergin气体和鬼暗能量的双组分宇宙。在第三个模型中,我们考虑另一个双组分宇宙,包括粘性的修正宇宙Chaubergin气体和鬼暗能量。在双组分流体的情况下,我们还考虑了组分之间相互作用的可能性。

英文摘要:

In this paper, we consider three different models of dark energy in higher dimensional space-time and discuss about some cosmological parameters numerically. The first model is a single component universe including viscous varying modified Chaplygin gas. In the second model, we consider two-component universe including viscous varying modified Chaplygin gas and ghost dark energy. In the third model, we consider another two-component universe including viscous modified cosmic Chaplygin gas and ghost dark energy. In the cases of two-component fluids we also consider possibility of interaction between components.
