摘要
讨论了复变函数的解析点与孤立奇点的运算性质,并给出了简单的证明。利用这些性质可以快速准确地判定某些复变函数的孤立奇点的类型,这对研究某些复变函数在其孤立奇点处的去心邻域内的性质、复积分的计算等是很有意义的。
This paper discusses operational properties of analytic point and isolated singularity of complex function and gives out simple proofs about them.By the properties,we can decide the type of isolated singularity of some complex functions.This is very meaningful for the researcher about the properties of isolated singularity in the deleted neighborhood and the computation of complex integration.
