中文简介:	通过对Hurwitz理论的时间顺序回顾，我们调查了一些已知的结果，列举了几种类型的表面分支覆盖物的等价类别。特别地，将提及与几种类型的图形覆盖物的等价类别的列举的关系，并列举不可定向表面的分支可定向表面覆盖物的同构类别。我们还讨论了具有规定分支类型的分支覆盖物的类似问题。
课程简介:	With a chronological review of Hurwitz theory, we survey some known results on the enumeration of the equivalence classes of several types of branched coverings of a surface. In particular, relations with the enumeration of the equivalence classes of several types of graph coverings and enumerating the isomorphism classes of branched orientable surface coverings of a nonorientable surface will be mentioned. Also we discuss a similar problem for branched coverings having prescribed branched types.
