Separation of variables and integral manifolds in one problem of motion of generalized Kowalevski top

Mikhail P. Kharlamov, Alexander Y. Savushkin

摘要:

在描述双常力场中Kowalevski型陀螺运动的三自由度可积Hamilton系统的相空间中,指出四维不变流形。它表明,该流形由临界运动生成的分支图的光滑片,和诱导动力系统是Hamilton与某些子集的辛结构的退化点。我们找到了这个系统中分离变量的变换。因此,解可以用时间的椭圆函数表示。相应的相拓扑结构进行了完整的描述。

英文摘要:

In the phase space of the integrable Hamiltonian system with three degrees of freedom used to describe the motion of a Kowalevski-type top in a double constant force field, we point out the four-dimensional invariant manifold. It is shown that this manifold consists of critical motions generating a smooth sheet of the bifurcation diagram, and the induced dynamic system is Hamiltonian with certain subset of points of degeneration of the symplectic structure. We find the transformation separating variables in this system. As a result, the solutions can be represented in terms of elliptic functions of time. The corresponding phase topology is completely described.
