用$Ω>1$研究缀片宇宙学中的快子宇宙
Tachyonic Universes in Patch Cosmologies with $Ω>1$
摘要:
本文利用快子场研究封闭的暴胀宇宙模型。我们描述了一种在斑块宇宙学中用$Ω>1$创造宇宙的一般处理方法,它能代表广义相对论、Gauss-Bonnet或Randall-Sundrum斑块。我们使用最近的天文观测数据来约束出现在我们的模型中的参数。
英文摘要:
In this article we study closed inflationary universe models by means of a tachyonic field. We described a general treatment for created a universe with $Ω>1$ in patch cosmology, which is able to represent General Relativity, Gauss-Bonnet or Randall-Sundrum patches. We use recent data from astronomical observations to constrain the parameters appearing in our model.
