On the Uniqueness of Certain Type of Difference Polynomial Sharing a Small Function
Subscribe/Renew Journal
The purpose of this paper is to study the uniqueness problems of certain type of difference polynomial sharing a small function. In this paper, we not only point out some gaps in the proof of the main results in [14], but also rectify the errors and present our main results in a more compact way. Also we exhibit two examples to show that one of the conditions of our result is the best possible.
Keywords
Meromorphic Function, Difference Polynomial, Uniqueness.
