Further Results on the Uniqueness of Meromorphic Functions and their Derivative Counterpart Sharing One or Two Sets

Abstract

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].

Key words and phrases. Meromorphic function, Unique Range Sets, shared sets, weighted sharing.
