Abstract:

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.

Key words: analytic point, moving singularity, pole, essence singularity
