涉及重级零点的亚纯函数的拟正规定则

设F为区域D内的只有重级零点的亚纯函数族,H(z)为区域D内的非常数亚纯函数,且存在v∈N,使得对于任意的a∈C,n(D,1/H(z)-a)≤v.如果对于任意的f∈F,f′(z)≠H′(z),那么F在区域D内v阶拟正规.     

分担一个亚纯函数的亚纯函数族的正规定则

Let F be a family of meromorphic functions in D,and let Ψ(≠0) be a meromorphic function in D all of whose poles are simple.Suppose that,for each f ∈F,f≠0 in D.If for each pair of functions {f,g}(?) F,f' and g' share Ψ in D,then F is normal in D.
