We obtain subordination, superordination and sandwich-preserving new theorems for certain integral operators defined on multivalent functions. The sandwich-type theorem for these integral operators is also derived and our results extend some earlier ones. Combining these new theorems with some previous related results, we give interesting subordination and superordination consequences for a wide class of analytic integral operators. |
