Abstract: |
The problem of uniqueness for meromorphic functions concerning differential polynomials sharing two values with some finite weighted was studied using the idea of weight-sharing value. The obtained results extend the theorems of Fang M. and Hong W,, et al. |
Key words: meromorphic function weight-sharing value uniqueness |
