Uniqueness of homogeneous differential polynomials of meromorphic functions concerning weakly weighted sharing

Abstract

. In 2006 S. Lin and W. Lin [3] fi rst de fi ned the concept of weakly-weighted sharing of functions and proved some results on uniqueness of a meromorphic function f and its n -th derivative f ( n ) . Using this notion of weakly-weighted sharing of functions, in this paper we prove uniqueness of homogeneous differential polynomials P [ f ] and P [ g ] generated by mero- morphic functions f and g respectively.
