Belinski-Khalatnikov-Lifshitz情景下动力学的一般不稳定性

Generic instability of the dynamics underlying the Belinski-Khalatnikov-Lifshitz scenario

Piotr Goldstein, Włodzimierz Piechocki

摘要:

一类精确解的Belinski-Khalatnikov-Lifshitz(BKL)的情况下,推导和测试其对小扰动的稳定性。这些是唯一的正规解决方案在Painlevé意义。我们证明了它们在宇宙奇点附近是不稳定的。的动态规律性也检查与动力系统方法。我们的结果证实了BKL的猜想,即奇异点附近的动力学变得一般混沌。

英文摘要:

A class of exact solutions to the Belinski-Khalatnikov-Lifshitz (BKL) scenario is derived and tested for their stability against small perturbations. These are the only regular solutions in the Painlevé sense. We prove that they are unstable in the vicinity of the cosmological singularity. Regularity of the dynamics is also examined with the dynamical systems method. Our results confirm the conjecture of BKL that the dynamics near the singularity becomes generically chaotic.
