Abstract

In this paper, we prove two theorems establishing the uniqueness of the derivatives of meromorphic functions f(k) and g(k) when they share two sets with least cardinalities. Our results improve some existing results of Fang–Lahiri, Banerjee–Bhattacharjee, Banerjee–Mallick and Banerjee–Chakraborty.
