摘要
The paper gives a necessary and sufficient condition that the sectionally stric-tly monotone continuous mapping that deg(f) =0 on S1 exists every order itera live roots, and gets that f exists every order iterative roots is equivalent to can be embedded in a quasi -semiflow .
本文给出了圆周上dege(f)=0的分段严格单调的连续映射f存在任意阶迭代根的充分必要条件,得出了f存在任意阶迭代根等价于可以嵌入一个拟半流的结论.
