FURTHER RESULTS ON THE UNIQUENESS OF MEROMORPHIC FUNCTIONS AND THEIR DERIVATIVE COUNTERPART SHARING ONE OR TWO SETS

In this paper we prove a number of results concerning uniqueness of a meromorphic function as well as its derivative sharing one or two sets. In particular, we deal with the specific question raised in [18], [19], [20] and ultimately improve the result of Banerjee-Bhattacharjee [4].
