Abstract

Our purpose in this paper is to define a linear operatorĀ  F_{p,q,s}[\alpha_{1},m], then applying it to obtain some results on subordination and superordination preserving properties of holomorphic multivalent functions in theĀ  open unit disc. And sandwich-type result for these holomorphic multivalent functions is also considered.
