摘要 设F为区域D内的一个全纯函数族,k(≥2)是一正整数,p是小于k的正整数,K为一正数.若对于任意的f∈F,f与f′CM分担zp,且当f(z)=zp,z∈D时,有∣f(k)(z)∣≤K,则F在D上是正规的. Let F be a family of holomorphic functions in a domain D, k(≥2) and p( 〈 k) be positive integers, and let K be a positive number. If, for each f∈F,z∈D, f and f' shared z^p CM,and | f^(k)(z) |≤K whenever f(z) =z^p in D,F is normal in D.
