刚体动力学中经典可积系统的拓扑分析

Topological analysis of classical integrable systems in the dynamics of the rigid body

M. P. Kharlamov

摘要:

刚体动力学中的一般可积性情况是拉格朗日、欧拉、科瓦列夫斯卡娅和戈里亚切夫-查波金的解。前两个可以包括在Smale的计划,研究自然系统的相拓扑的对称性。我们修改Smale的程序,以适应最复杂的最后两种情况下的非线性首次积分。找到了分歧集,并对积分环的所有变换进行了描述和分类。在Kovalevskaya和Goraychev-Chaubergin情形下建立了环面的新的非平凡分支。

英文摘要:

The general integrability cases in the rigid-body dynamics are the solutions of Lagrange, Euler, Kovalevskaya, and Goryachev-Chaplygin. The first two can be included in Smale's scheme for studying the phase topology of natural systems with symmetries. We modify Smale's program to suit the most complicated last two cases with non-linear first integrals. The bifurcation sets are found and all transformations of the integral tori are described and classified. New non-trivial bifurcation of a torus is established in the Kovalevskaya and Goraychev-Chaplygin cases.
