含不定常扰动参数的平均

Averaging with a time-dependent perturbation parameter

David Fajman, Gernot Heißel, Jin Woo Jang

摘要:

受最近数学宇宙学问题的启发,其中时间平均方法被应用于分析具有振荡行为的模型的未来渐近性,我们提供了一个关于一般类系统解的大时间行为的定理。因此,我们建议我们的结果是适用于广泛的问题,在空间均匀的宇宙学振荡行为。在数学上,该定理建立在非线性动力系统的平均标准理论之上。

英文摘要:

Motivated by recent problems in mathematical cosmology, in which temporal averaging methods are applied in order to analyze the future asymptotics of models which exhibit oscillatory behavior, we provide a theorem concerning the large-time behavior for solutions of a general class of systems. We thus propose our result to be applicable to a wide range of problems in spatially homogenous cosmology with oscillatory behavior. Mathematically the theorem builds upon the standard theory of averaging in non-linear dynamical systems.
