摘要

我们用动力学系统的公式来考虑齐次宇宙学向未来的演化。使用变分方程方法，我们证明了在Mixmaster时代结束和随后的Friedmannian状态之间存在短暂的瞬态解。简要讨论了对未来的一般非均匀演化、重迭问题、视界问题和通货膨胀所需的初始条件的影响。

Dynamical Synchronization, the Horizon Problem, and Initial Conditions for Inflation

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.
