LIU, FANGHONG; YI, HONGXUN;

Abstract
In this article, we main study the uniqueness problem of meromorphic function which difference polynomials sharing common values. We consider the entire function $\small{(f^n(f^m-1)\prod_{j=1}^{s}f(z+c_j)^{{\mu}j})^{(k)}}$ and the meromorphic function $\small{f^n(f^m-1)\prod_{j=1}^{s}f(z+c_j)^{{\mu}j}}$ to get the main results which extend Theorem 1.1 in paper[5] and theorem 1.4 in paper[6].
