关于亚纯函数的正规族

摘要

In this paper, we study the normality of meromorphic functions, by using Zalcman lemma, obtain some normality criteria of families of meromorphic functions, which respectively improve and generalize the related results of Gu [4] and Bergweiler [1].%在本文研究了亚纯函数族的正规族问题,利用Zalcman引理的方法,获得了亚纯函数族的几个正规定则.并改进了顾永兴和Bergweiler的结果.
