Some Properties of Multivalent Functions Associated with a Certain Operator

Abstract

We obtain some subordination and superordination results involving a new operator. By means of the new introduced operator $\mathrm{C}_{p,n}^{\lambda }(a,c)f(z),$ for some multivalent functions in the open unit disc, we establish the differential sandwich theorem.
