摘要
复变初等函数的多值性是由其辐角函数的多值性引起的,利用辐角函数的特性,判定初等多值函数的支点与支割线,解决一些初等多值函数的单值分支问题.
The multi-valued property of elementary multiple valued complex function arises from its argument function.By applying the property of argument functions,the judgment of branch points and branch line of the elementary multiple valued complex function is presented.The method to solve the one-valued branch for some elementary multiple valued complex functions is given too.
