摘要:假设F是区域DC的一亚纯函数族.设k(≥2)是一个正整数,且a,b,c,d是4个相互判别的有限复数并满足c≠0,d≠a,c≠b.对每个函数f∈F,如果f-a所有的零点的重级不小于k,且f(k)=b当且仅当f=a,f(k)=c当f=d,那么F在D内正规.

Abstract: Let F  be a family of meromorphic functions in a domain DC,let k≥2 be a positive integer,and a,b,c,d be four finite complex numbers such that c≠0,d≠a,c≠b.If for every f∈F,all zeros of f-a have multiplicity at least k,and f(k)=b if and onl
y if f=a,and f =d whenever f(k)=c,then F is normal in  D.

Key words: meromorphic function, share value, normality
