A Class of Integral Operators Preserving Subordination and Superordination for Analytic Functions

الملخص EN

The purpose of the paper is to investigate several subordination- and superordination-preserving properties of a class of integral operators, which are defined on the space of analytic functions in the open unit disk.

The sandwich-type theorem for these integral operators is also presented.

Moreover, we consider an application of the subordination and superordination theorem to the Gauss hypergeometric function.
