宇宙真实模型中空间曲率的几何数量级估计

Geometrical order-of-magnitude estimates for spatial curvature in realistic models of the Universe

Thomas Buchert, George F R Ellis, Henk van Elst

摘要:

本文所表达的思想基于Jürgen Ehlers于2007年7月在德国Golm的Albert-Einstein研究所发表的评论。本文的主要目的是证明,在合理的几何标量的数量级估计,空间曲率的相关性,在现实的宇宙模型,描述的结构形成的动力学,因为时代的物质辐射去耦。我们介绍这些估计与评论使用的准牛顿度量形式在这种情况下。

英文摘要:

The thoughts expressed in this article are based on remarks made by Jürgen Ehlers at the Albert-Einstein-Institut, Golm, Germany in July 2007. The main objective of this article is to demonstrate, in terms of plausible order-of-magnitude estimates for geometrical scalars, the relevance of spatial curvature in realistic models of the Universe that describe the dynamics of structure formation since the epoch of matter-radiation decoupling. We introduce these estimates with a commentary on the use of a quasi-Newtonian metric form in this context.
