Motivated by the theory of Painlevé equations and associated hierarchies, we study nonautonomous Hamiltonian systems that are Frobenius integrable. We establish sufficient conditions under which a given finite-dimensional Lie algebra of Hamiltonian vector fields can be deformed into a time-dependent Lie algebra of Frobenius integrable vector fields spanning the same distribution as the original algebra. The results are applied to quasi-Stäckel systems from [14].

变形李代数与Frobenius可积非自治哈密顿系统。
受Painlevé方程和相关层级理论的推动,我们研究了Frobenius可积的非自治哈密顿系统。我们建立了充分的条件,在此条件下,哈密顿向量场的给定有限维李代数可以变形为与原始代数相同分布的Frobenius可积向量场的时变李代数。将结果应用于[ 14]中的准Stäckel系统。
