关于分担值的正规族

Normal families concerning shared values

推广了设F是区域D内的全纯函数族,a和b是2个有穷复数,且b≠a,0,若对于F中的任意函数f=a■f′=a,f′=b■f=b,则F在D内正规的一个正规定则,得到了亚纯函数族的一个正规定则。

In this paper, we obtain a normality criteria for a family of meromorphic functions, which extends letF be a family of holomprphic functions in a domain D, and let a and b be two fmite complex numbers such that b ≠ a, 0. If foreach f∈F,f=a→f′=a,f′=b→f=b,then Fisnormal.
