摘要 针对一类零点个数为有限的全纯函数族,在函数与其导函数分担一个极点均为重级的亚纯函数的条件下,利用Nevanlinna理论及其方法改进了已有文献在分担值条件下得到的一个定理. In this paper, a class of holomorphic functions with finite number of zeros is studied,undering the condition that functions and their derivatives share a meromorphic function with multiple poles. A theorem obtained under the condition of sharing values is improved by using Nevanlinna theory and its method.
