正常谐振环的拟周期稳定性

Quasi-periodic stability of normally resonant tori

Henk W. Broer, M. Cristina Ciocci, Heinz Hanßmann, André Vanderbauwhede

摘要:

我们研究下的正常内共振,可能有多个特征值的准周期环面。两个非简并条件起作用。其中第一个推广的Floquet矩阵的可逆性,并防止漂移的低维环面。第二个条件涉及一个Kolmogorov样的内部频率的变化,同时versality的Floquet矩阵展开。我们专注于可逆的设置,但我们的结果进行到哈密顿和耗散的背景下。

英文摘要:

We study quasi-periodic tori under a normal-internal resonance, possibly with multiple eigenvalues. Two non-degeneracy conditions play a role. The first of these generalizes invertibility of the Floquet matrix and prevents drift of the lower dimensional torus. The second condition involves a Kolmogorov-like variation of the internal frequencies and simultaneously versality of the Floquet matrix unfolding. We focus on the reversible setting, but our results carry over to the Hamiltonian and dissipative contexts.
