对称背景下大爆炸奇点的初始数据

Initial data on big bang singularities in symmetric settings

Hans Ringström

摘要:

在最近的一篇文章中,我们提出了大爆炸奇点初始数据的一般几何概念。这一概念本身就很有意义。然而,它也提供了一个统一的观点在文献中的许多结果的目的。在本文中,我们给出了一个部分的理由,这一说法的改写的结果有关Bianchi类A正交刚性解决方案和解决方案的$\mathbb{T}^{3}$ -Gowdy对称真空设置在我们的一般几何概念的初始数据的大爆炸奇点。

英文摘要:

In a recent article, we propose a general geometric notion of initial data on big bang singularities. This notion is of interest in its own right. However, it also serves the purpose of giving a unified perspective on many of the results in the literature. In the present article, we give a partial justification of this statement by rephrasing the results concerning Bianchi class A orthogonal stiff solutions and solutions in the $\mathbb{T}^{3}$-Gowdy symmetric vacuum setting in terms of our general geometric notion of initial data on the big bang singularity.
