摘要：
The paper deals with the problem of determining some sufficient conditions under which a polynomial generated by a meromorphic function and its k-th derivative sharing a set become identical. In this context, we have somehow been able to present an unique range set for a special class of meromorphic functions with smallest cardinalities. We have exhibited a number of examples relevant to the content of the paper. © 2018, Springer-Verlag Italia S.r.l., part of Springer Nature.
