On the characteristics of meromorphic functions with three weighted sharing values

In this paper, we deal with the relation between the characteristic function of two nonconstant meromorphic functions with three weighted sharing values, which improves a result given by H.X. Yi and Y.H. Li. From this we establish a theorem which improves a result given by P. Li and C.C. Yang. © 2006 Elsevier Inc. All rights reserved
