Subclass of Multivalent -Uniformly Functions with Varying Arguments [PDF]

open access: yesJournal of Mathematics, 2013
We introduce a class of multivalent -uniformly functions with varying arguments, give some properties of functions in this class, and obtain sharp results including coefficient estimates and distortion theorems.

Some Subclasses of Spirallike Multivalent Functions Associated with a Differential Operator

open access: yesMathematics, 2022
In this paper we study convolution properties of spirallike multivalent functions defined by using a differential operator and higher order derivatives. Using convolution product relations we determine necessary and sufficient conditions for multivalent ...

Applications of Higher-Order Derivatives to the Subclasses of ‎Meromorphic Starlike Functions [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
In this paper, we introduce and study some new classes of multivalent (p -valent) meromorphically starlike functions involving Higher-Order derivatives. For these multivalent classes of functions, we derive several interesting properties including sharp ...

Some geometric properties of multivalent functions associated with a new generalized $ q $-Mittag-Leffler function

open access: yesAIMS Mathematics, 2022
In this article, a new generalized $ q $-Mittag-Leffler function is introduced and investigated. Motivated by the newly defined function and using the concept of differential subordination, a new subclass of multivalent functions is introduced.

Differential Subordination and Differential Superordination for Classes of Admissible Multivalent Functions Associated with a Linear Operator

open access: yesMathematics, 2022
In this paper, we first introduce a linear integral operator ℑp(a,c,μ)(μ>0;a,c∈R;c>a>−μp;p∈N+:={1,2,3,⋯}), which is somewhat related to a rather specialized form of the Riemann–Liouville fractional integral operator and its varied form known as the ...

Multivalent Functions and Differential Operator Extended by the Quantum Calculus

open access: yesFractal and Fractional, 2022
We used the concept of quantum calculus (Jackson’s calculus) in a recent note to develop an extended class of multivalent functions on the open unit disk. Convexity and star-likeness properties are obtained by establishing conditions for this class.

Some New Results of Differential Subordinations for HigherOrder Derivatives of Multivalent Functions

open access: yes, 2021
The main purpose of this paper is to study the differential subordination result for multivalent analytic functions. We give some applications of higher-order differential subordination results involving Hadamard product for multivalent analytic ...

A generalized conic domain and its applications to certain subclasses of multivalent functions associated with the basic (or $ q $-) calculus

open access: yesAIMS Mathematics, 2021
In this paper, by using the concept of the basic (or q-) calculus and a generalized conic domain, we define two subclasses of normalized multivalent functions which map the open unit disk: U = {z : z ∈ C and |z| < 1} onto this generalized conic domain ...
