Abstract
The purpose of the present paper is to derive several subordination, superordination results, and sandwich results for the function of the form $f\left(z\right)=z+\sum^{\infty }_{n=2}{a_nz^n}$ which is univalent in the open unit disc $\ U=\left\{z\in \mathbb{C}:\left|z\right|.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
