自引力黎曼液体椭球的不可积性
Non integrability of a self-gravitating Riemann liquid ellipsoid
摘要:
我们证明了无角动量的均匀液体的三轴Riemann椭球的运动不具有附加的首次积分,该第一积分在位置、冲量和出现在势中的椭圆函数上是亚纯的,因此是不可积的。我们还证明了这个系统即使在一个固定的能级超曲面上也是不可积的。
英文摘要:
We prove that the motion of a triaxial Riemann ellipsoid of homogeneous liquid without angular momentum does not possess an additional first integral which is meromorphic in position, impulsions, and the elliptic functions which appear in the potential, and thus is not integrable. We prove moreover that this system is not integrable even on a fixed energy level hypersurface.
