Certain subclasses of Spiral-like univalent functions related with Pascal distribution series

open access: yesMoroccan Journal of Pure and Applied Analysis, 2021
The purpose of the present paper is to find the sufficient conditions for the subclasses of analytic functions associated with Pascal distribution to be in subclasses of spiral-like univalent functions and inclusion relations for such subclasses in the ...

Conformable differential operators for meromorphically multivalent functions

open access: yesConcrete Operators, 2021
We define a conformable diff-integral operator for a class of meromorphically multivalent functions. We show that this conformable operator adheres to the semigroup property.

On sandwich theorems for some subclasses defined by generalized hypergeometric functions [PDF]

open access: yes, 2017
In this paper we derive some subordination and superordination results for certain normalized analytic functions in the open unit disc, which are acted upon by a class of generalized hypergeometric function Hq,s(α1).

Sufficient conditions for analytic functions defined by Frasin differential operator [PDF]

open access: yes, 2022
In this paper, by making use of a new differential operator, we derive a new sufficient conditions for analytic functions in the open unit disk. Several corollaries of the main result are also considered.
