Abstract

30A20 30A40 30C45 30C80 analytic function, convex function differential subordination and superordination integral operator subordination chain
We obtain subordination, superordination and sandwich-preserving new theorems for certain integral operators defined on the space of normalized analytic functions in the open unit disk. The sandwich-type theorem for these integral operators is also derived, and the results generalize some recently ones.
