一类有13阶结点的五次系统的定性分析

Analysis of the Fifth Systems with Thirteenth Order Node Point

本文讨论了一类带有一个零特征根的13阶结点的平面五次系统的全局结构,并 给出射影平面上的所有可能的局部相图.

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