关于分担值与正规性的─点注记

A NOTE ON SHARING VALUES AND NORMALITY

本文证明了如下定理：设是区域Ｄ内的一族亚纯函数，ａ是一非零有穷复数，ｋ是一正整数。若对于任意有在Ｄ内ｆ≠０且ｆ与ｆ（ｋ）分担ａ，则在Ｄ内正规．

In this paper,we prove the following theorem:Let be a be a family of meromorphic in a domain D and a be a finite non-zero complex number, k be a positive integer. If f and f￣(k) share a and f≠O in D for every ,then then is mormal in D
