| چکیده | ||
| In the present paper, we obtain some subordination and superordination results, involving the operator $T^{a}$ for functions of the form $f(z)=z^{-1}+\sum_{k=1}^{\infty}a_k z^{k}$, which are meromorphic univalent in the punctured open unit disk these results are applied to obtain sandwich results. | ||
