Uniqueness of certain type of differential-difference and difference polyniminals

Abhijit Banerjee, Sujoy Majumder


In this paper we consider certain difference and differential-difference polynomials sharing some polynomial and improve a number of results in \cite{8a}, \cite{8aa} and \cite{18}. In particular we point out a gap in the argument in the proof of the main results in \cite {8aa} and rectifying the same we improve and extend the result to a large extent.
