摘要
在Gaus球面上,讨论了Lienard系统的拓扑分类问题,证明了系统有且只有两个奇点0和∞,及C类轨线和D类轨线的可能分布情况.
The problem of topological classification to Lienard systems is discussed on Gauss sphere in this paper. It is showed that the system has two and only two singnlar points 0 and ∞. The distribution of C -trajectories and D -trajectories is also discussed.
