一类有15阶结点的五次系统的全局结构

Global structures of a class of fifth systems with fifteenth order node point

讨论了一类带有两个零特征根的15阶结点的平面五次多项式微分系统的全局结构,并给出了射影平面上的所有相图.

The global structures of a class of the plane fifth polynomial differential systems with a fifteenth order node point of two zero eigenvalues are discussed.All the phase diagrams on the projective plane are given.
