正常曲率旋转曲面上Kepler问题的块正则化
Block regularization of the Kepler problem on surfaces of revolution with positive constant curvature
摘要:
我们考虑同胚于$S^2$且具有常高斯曲率的旋转曲面上的开普勒问题。我们表明,该系统是最大的超可积,发现常数的运动推广的龙格-伦茨矢量。然后,使用这样的第一积分,我们确定类的表面,导致块正则化碰撞奇点。特别是,我们表明,奇点总是正则化的,如果表面是球面orbifolds的革命与常曲率。
英文摘要:
We consider the Kepler problem on surfaces of revolution that are homeomorphic to $S^2$ and have constant Gaussian curvature. We show that the system is maximally superintegrable, finding constants of motion that generalize the Runge-Lentz vector. Then, using such first integrals, we determine the class of surfaces that lead to block-regularizable collision singularities. In particular we show that the singularities are always regularizable if the surfaces are spherical orbifolds of revolution with constant curvature.
