本文的目的是给出非临界Bely-ĭ定理的一个有效形式。也就是说,我们计算了在规定的有限点集上非分支的正特征Bleyĭ映射的最小分枝次数的一个显式界。
The purpose of the present paper is to give an effective version of the noncriticalp-tame Belyĭ theorem. That is to say, we compute an explicit bound on the minimal degree of tamely ramified Belyĭ maps in positive characteristic which are unramified at a prescribed finite set of points.
