来自五维真空的宇宙学暗流体

Cosmological dark fluid from five-dimensional vacuum

Luz M. Reyes, José Edgar Madriz Aguilar, L Arturo Ureña-López

摘要:

在引力诱导物质理论的框架下,我们导出了场方程的5D解,该解可以描述暗流体(暗物质加暗能量)状态方程具有几何起源的4D宇宙学场景。没有一个自然的分离暗扇区到不同的组件,然后该模型可以提供一个几何解释暗简并在宇宙学场景中的存在。

英文摘要:

In the framework of the induced matter theory of gravity, we derive a 5D solution of the field equations that can describe a 4D cosmological scenario where the dark fluid (dark matter plus dark energy) equation of state has a geometrical origin. There is no a natural separation of the dark sector into different components, and then the model may provide a geometrical explanation for the existence of a dark degeneracy in cosmological scenarios.
