• Differential Subordination and Superordination For Analytic Functions Defined Using A Family Of Generalized Differential Operators

Amnah Shammaky*

Abstract


By making use of the generalized differential operator, the authors derive the subordination and superordination results for certain normalized analytic functions in the open unit disk. Many of the well-known and new results are shown to follow as special cases of our results.

Keywords


Analytic functions, Differential Operators, Differential Subordination, Differential Superordination.
