Sandwich theorems for analytic univalent functions defined by Hadamard product operator

In the present paper, we obtain some subordination and superordination results involving the Hadamard product operator D^{\mu,b}_{\alpha,c} for certain normalized analytic univalent functions in the open unit disk. These results are applied to obtain sandwich results.
