【摘要】 <正> §1.在[3]中,已对一类平面三次系统(?) (1.1)的无穷远奇点进行了讨论,并作出了相应的拓扑分类。本文将对一般的平面三次系统;(?) (1.2)更多还原

【Abstract】 This paper is a continuation of the paper （I）. We consider the system dx/dt=∝x+βy +b₁x²+b₂xy+b₃y²+b₄x³+b₅x²y+b₆xy²+b（?）y³ dz/dt=γx+βy+a₁x²+a₂xy+a₃y²+a₄x³+a₅x²y+a₆xy²+a₇y³ （1） Using the theory of an analysis of singular poiuts in no-linear differential equations, we give clasifications of singulaar points at infinite for（1）。Our res- ults can provide tools for study of the qualitative proportions of flows to planar cubic system。更多还原
