近线性Hamilton算子的最优稳定性和不稳定性

Optimal stability and instability for near-linear Hamiltonians

Abed Bounemoura

摘要:

本文证明了线性可积哈密顿系统扰动稳定性的一个非常一般的结果,并构造了一个不稳定性的例子,说明我们的结果和例子都是最优的。此外,在相同的精神,作为KAM稳定的可积哈密顿量的概念,我们将引入有效稳定的可积哈密顿量的概念,猜想这些哈密顿量的特征,并表明我们的结果证明了这一猜想在线性情况下。

英文摘要:

In this paper, we will prove a very general result of stability for perturbations of linear integrable Hamiltonian systems, and we will construct an example of instability showing that both our result and our example are optimal. Moreover, in the same spirit as the notion of KAM stable integrable Hamiltonians, we will introduce a notion of effectively stable integrable Hamiltonians, conjecture a characterization of these Hamiltonians and show that our result prove this conjecture in the linear case.
