Hankel determinants for q-starlike functions connected with q-sine function

Demonstratio Mathematica
This article comprises the study of a new class of starlike functions, which is defined by qq-fractional operator and subordination to the qq-analog of sine function.

On a subclass of multivalent functions defined by generalized multiplier transformation

Open Mathematics
The objective of this study is to establish a novel category of multivalent analytic functions by utilizing generalized multiplier transformations. The subclass is further examined for coefficient estimations, growth and distortion theorems, extreme ...

Designing Filter for Certain Subclasses of Analytic Univalent Functions [PDF]

In this paper we consider certain subclasses of analytic univalent functions and plot a frequency response of appropriate circuit for both amplitude and phase with changing source frequency.

Coefficient functionals for Sakaguchi-type-Starlike functions subordinated to the three-leaf function

Demonstratio Mathematica
A challenging part of studying geometric function theory is figuring out the sharp boundaries for coefficient-related problems that crop up in the Taylor-Maclaurin series of univalent functions.

On the starlikeness of iterative integral operators [PDF]

, 2016
The main object of the present paper is to investigate starlikeness of certain integral operators‎, ‎which are defined here by means of iterative in the‎ ‎open disk $\mathbb{D}_R=\{z\in\mathbb{C}:|z|<R\}$ with $R\geq1$‎.

Analytic solutions of a generalized complex multi-dimensional system with fractional order

Demonstratio Mathematica
The Duhamel principle is a mathematical principle that allows us to solve linear partial differential equations. This system is generalized by the concept of the kk-symbol fractional calculus.

On a subclass of convex functions [PDF]

, 2016
In this paper we study a subclass of convex functions. Among others we prove an interesting property regarding the composition of functions from this class. The basic tool of the proof is the theory of differential subordination.

Hankel determinant of order three for familiar subsets of analytic functions related with sine function

Open Mathematics, 2019
In this paper we define and consider some familiar subsets of analytic functions associated with sine functions in the region of unit disk on the complex plane. For these classes our aim is to find the Hankel determinant of order three.

Properties of a new integral operator

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper, we derive sufficient conditions for the univalence, star- likeness, convexity and some other properties in the class N (ρ) ; for a new integral operator defined on the space of normalized analytic functions in the open unit disk.
