在改进亚纯函数权分担值方式的情形下,讨论了亚纯函数及其n阶导数权分担两个值的问题,得到两个亚纯函数唯一性定理,改进了先前的结果.
This paper investigates the uniqueness problem of whether or not meromorphic functions and their derivatives share two values with weight. Under a set of weaker conditions compared to the pre vious studies it obtains the same results,thus improving the previous results.
