摘要
得到了广义旋转向量场与常微分方程第二比较定理之间的局部等价关系。运用这个等价关系,可简化广义旋转向量场有关结论的证明。
In this paper we obtain the local equivalence between generalized rotated vector fields and the second comparison theorem of ordinary differential equations. Thus the proof of some results of generalized rotated vector fields can be simplified by the second comparison theorem.
