| Abstract: |
| In this paper, we investigate the uniqueness of the derivatives of meromorphic functions sharing two different sets, and obtain the result that if two transcendental meromorphic functions $f$ and $g$ satisfy $\overline{E}_{f^{(k)}}(S)=\overline{E}_{g^{(k)}}(T)$, then $f^{(k)}=Ag^{(k)}$, where $S$, $T$ are two finite sets and $A$ is a nonzero constant. In particular, $k=0$ implies $f=Ag$. |
