Abstract

In this paper, we study the uniqueness problems on entire functions sharing one value. We improve and generalize some previous results of Zhang and Lin [11]. On the one hand, we consider the case for some more general differential polynomials $[ f^{n}P(f)] ^{(k) }$ where $P(w)$ is a polynomial; on the other hand, we relax the nature of sharing value from CM to IM.

Keywords: uniqueness, entire function, sharing value
