【期刊论文】MEROMORPHIC FUNCTIONS AND ALSO THEIR FIRST TWO DERIVATIVES HAVE THE SAME ZEROS
杨连中, Lian-Zhong Yang
Annales Academiae Scientiarum Fennicae Mathematica Volumen 30, 2005, 205-218,-0001,():
-1年11月30日
In this paper, we present a uniqueness theorem of meromorphic functions which together with theirrst two derivatives have the same zeros, this generalizes a result of C. C. Yang. As applications, we improve a result of L. Kohler, and answer a question of Hinkkanen in more weak conditions for meromorphic functions of hyper-order less than one, and we supply examples to show that the order restriction is sharp.

设F为区域G上的全纯函数族,a,6(≠0)为两有穷复数,n为正整数。本文推广了Miranda定则,证明了:若对任意的f ∈F,(a,b)为,与,f(n)在G上的IM分担数组,且当f=a时,f'=f(n+1)=6,则F在G中正规。
