摘要:

通常所说的代数体函数都是由不可约方程确定出来的. 最近, 孙与高[1-2]研究代数体函数的四则运算时把这一要求去掉了. 该文对可约方程确定出来的代数体函数进行了研究, 探讨了其单值解析分支及分支点, 论证了代数体函数的第一、二基本定理及对数导数引理对于可约代数体函数同样成立.

关键词: 代数体函数, 可约, 基本定理

Abstract:

Algebroid functions are generally determined by the irreducible equations. Recently, Sun and Gao[1-2] have removed the request when they investigated the arithmetic operations of algebroid functions. In this paper, we study the algeroid functions determined by the reducible euqations. First, we discuss its single-valued branches and branch points, then show that the logarithmic derivative lemma, the first and second fundamental theorems of algeboird functions also apply to the reducible algeboid functions.

Key words: Algebroid function, Reducibility, Fundamental theorem
