摘要
本文研究了有穷级亚纯函数的导数及其差分分担值的唯一性问题,主要证明了以下结论:如果f′与△_cfCM分担a,b,∞,则f′≡△_cf.该结论解决了Qi等人在2018年提出的问题.
In this paper,we investigate a uniqueness of meromorphic functions with finite order concerning their derivative and difference and obtain one result that if f′and△_cf share a,b,∞CM,then f′≡△_c f.This result confirms the problem of Qi et al.in 2018.
