非自治线性Hamilton算子群的微分Galois分析

Group Analysis of Non-autonomous Linear Hamiltonians through Differential Galois Theory

David Blazquez-Sanz, Sergio A. Carrillo Torres

摘要:

本文引入了非自治意义下的可积性概念。对于1 + 1/2自由度和2 + 1/2自由度的二次齐次Hamilton算子,我们证明了这一概念等价于系统在扩展相空间中的经典完全可积性。对于自由度为2 + 1/2的二次齐次哈密顿量,我们也给出了Morales-Ramis结果的一个倒数。我们利用涉及时间代数函数的标架辛变换对这些系统进行了分类,并给出了它们的标准型。

英文摘要:

In this paper we introduce a notion of integrability in the non autonomous sense. For the cases of 1 + 1/2 degrees of freedom and quadratic homogeneous Hamiltonians of 2 + 1/2 degrees of freedom we prove that this notion is equivalent to the classical complete integrability of the system in the extended phase space. For the case of quadratic homogeneous Hamiltonians of 2 + 1/2 degrees of freedom we also give a reciprocal of the Morales-Ramis result. We classify those systems by terms of symplectic change of frames involving algebraic functions of time, and give their canonical forms.
