Uniqueness of meromorphic functions whose certain nonlinear differential polynomials share a polynomial

Abstract: In this paper, we get two uniqueness theorems of meromorphic functions whose certain nonlinear differential polynomials share a polynomial. The results in this paper extend the corresponding results given by Fang (2002) in . Our reasoning in this paper will correct a defective reasoning in the proof of Theorem 4 in Bhoosnurmath and Dyavanal (2007) . An example is provided to show that some conditions of the main results in this paper are necessary. [Copyright &y& Elsevier]
