Some Sandwich-Type Results for Analytic Functions Involving a Multiplier Transformation

Abstract

We investigate some classes of analytic functions defined on
$\mathbb{U}\times \mathbb{\overline{U}}$ to obtain new results on
a multiplier transformation, which involves the iterations of the
Owa-Srivastava operator and its combination, associated with strong
differential subordination and strong differential superordination
results for analytic functions on $\mathbb{U}\times
\mathbb{\overline{U}}$, $\mathbb{U}$ and $\mathbb{\overline{U}}$
being the open unit disk and its closure, respectively. Several
Sandwich-type results are also obtained.
