关于Tonelli Hamilton算子的可积性

On the Integrability of Tonelli Hamiltonians

Alfonso Sorrentino

摘要:

本文讨论了关于哈密顿系统可积性的刘维尔定理的一个弱形式。我们表明,在托内利哈密顿的情况下,对合假设的运动积分可以完全下降,仍然有趣的信息系统的动力学可以推导出来。此外,我们证明了在n维环面上,这个较弱的条件意味着经典的可积性的刘维尔意义。证明的主要思想是将托内利哈密顿量的运动的独立积分的存在与其马瑟集和奥布里集的大小相关联。作为一个副产品,我们指出存在的非平凡的共同不变集的所有哈密尔顿泊松交换与托内利之一。

英文摘要:

In this article we discuss a weaker version of Liouville's theorem on the integrability of Hamiltonian systems. We show that in the case of Tonelli Hamiltonians the involution hypothesis on the integrals of motion can be completely dropped and still interesting information on the dynamics of the system can be deduced. Moreover, we prove that on the n-dimensional torus this weaker condition implies classical integrability in the sense of Liouville. The main idea of the proof consists in relating the existence of independent integrals of motion of a Tonelli Hamiltonian to the size of its Mather and Aubry sets. As a byproduct we point out the existence of non-trivial common invariant sets for all Hamiltonians that Poisson-commute with a Tonelli one.
