Generalization of Uniqueness and Value Sharing of Meromorphic Functions Concerning Differential Polynomials

Abstract

The motivation of this paper is to study the uniqueness problems of meromorphic functions concerning differential polynomials that share a small function. The results of the paper improve and generalize the recent results due to Fengrong Zhang and Linlin Wu [13]. We also solve an open problem as posed in the last section of [13]
