Some sandwich theorems for meromorphic univalent functions defined by new integral operator

, 2021
The main goal of this paper is to obtain some sandwich-type results for the functions of the form: , which are meromorphic univalent in the punctured open unit disk U by using new integral operator.

On sandwich results of univalent functions defined by a linear operator

Journal of Interdisciplinary Mathematics, 2020
In the present paper, we obtain sandwich theorems for univalent functions by using some results of differential subordination and superordination for univalent functions involving linear operator.

Nonconvexities in Univalence

Mathematics of Operations Research, 1983
When a mapping is univalent (one-to-one) on a set is a question which has received considerable study. Much of the recent research has focused on the shape of the set on which the mapping is defined. It has been suggested, in fact, that the set must be convex for univalence to hold. This paper presents conditions under which the set need not be convex.
