摘要
一、引言我们称两个非常数亚纯函数f(z)和g(z)取得共同值a是指f(z)-a和g(z)-a具有相同的零点。有关亚纯函数及其导数取得共同值时的关系,Rubel和Yang在[5]中证明了定理A 如果整函数f和它的导数f′取得两个共同有穷值(计算重数),则f=f′。
In [2], G. G. Gundersen obtained some theorems on meromorphic functions that share same values with their derivative, we generalize and improve some of his results under the case related to multiplicity values,
