Uniqueness and value-sharing of differential polynomials of meromorphic functions

In this paper, we investigate uniqueness problems of meromorphic functions concerning differential polynomials sharing non-zero finite value and give some results. As particular cases of our results we deduce several earlier results of Fang and Hong (2001) [2], , Fang and Hua (1996) [1], , Lin and Yi (2004) [5], , Yang and Hua (1997) [6] and others.
