| Abstract: |
| In this paper, we obtain some normality criteria for families of meromorphic functions that concern the number of distinct zeros of the differential polynomial, which extends the related result of Li, and Chen et al.. An example is given to show that the hypothesis on the zeros of $a(z)$ is necessary. |
| Key words: Meromorphic function Normal family Differential polynomial Zero |
