公共值与正规定则

Sharing Values and Normality Criteria

设F为区域G上的全纯函数族，a，b为两个判别的有穷复数．本文证明了如果对任意的f∈F，a；b为f与f'在G上的IM公共值，则F在G上正规．

Let F be a family of holomorphic functions in a domain G; a,b be two distinct finite complex numbers. In this paper, we prove that F is normal in G if f and f' share a, b IM in G, for every f ∈ F.
