摘要:

F 为区域D上的亚纯函数族, S为具有三个元素的有穷复数集合, k 为大于2 的正整数, a为任何有穷复数. 若对\forall f ∈F, f-a 的零点和极点重数均 ≥k, 且\overline{E}(S, f)=\overline{E}(S, f (k), 则FD内正规.

关键词: 亚纯函数, 正规族, 分担集

Abstract:

Let F be a family of meromorphic functions in a domain D and S be a set consisting of three distinct elements. Let a be a finite complex number and k(>2) be a positive integer. If each f ∈F satisfies that the zeros and poles of f-a are of multiplicity ≥k and \overline{E}(S, f)=\overline{E}(S, f(k), then F is normal in D.

Key words: Meromorphic functions, Normal family, Shared set
