ON SANDWICH THEOREMS OF ANALYTIC FUNCTIONS INVOLVING NOOR-MULTIPLIER INTEGRAL OPERATOR

The Noor-Multiplier integral operator $I_{n,p}^{\delta}{f(z)}$ of n-th order of $f(z)$ is introduced, and some properties of this operator are provided by applying the methods based on the differential subordination and differential superordination. The results obtained generalize some results of earlier authors.
