论文摘要

我们考虑在动态系统配方中对未来的同质宇宙学的演变。使用差异方程方法,我们表明,在混合官时代结束和随后的弗里德曼尼亚国家之间存在短时间的短暂解决方案。简要讨论了对未来的通用不均匀进化的含义,回忆问题,地平线问题和通货膨胀所需的初始条件。

We consider the evolution of homogeneous cosmologies towards the future in a dynamical systems formulation. Using a variational equation approach, we show that there is a short period in which transient solutions between the end of a Mixmaster era and a subsequent Friedmannian state exist. Implications about the generic inhomogeneous evolution towards the future, the recollapse problem, the horizon problem, and the initial conditions required for inflation are briefly discussed.
