Stoïlow’s theorem from 1928 states that a continuous, open, and light map between surfaces is a discrete map with a discrete branch set. This result implies that such maps between orientable surfaces are locally modeled by power maps and admit a holomorphic factorization.
The purpose of this expository article is to give a proof of this classical theorem having readers in mind that are interested in continuous, open and discrete maps.

斯托伊洛定理再探
1928年的斯托伊洛定理指出,曲面之间的连续,开放和光照贴图是具有离散分支集的离散贴图。该结果表明,可定向曲面之间的此类贴图由功率贴图局部建模。 并接受全纯分解。
这篇说明性文章的目的是在考虑到对连续,开放和离散地图感兴趣的读者的情况下,提供这一经典定理的证明。
