Study of quantum calculus for a new subclass of bi-univalent functions associated with the cardioid domain [PDF]

open access: yesHeliyon
In this article, we make use of the concepts of subordination and the q-calculus theory to analyze a new class of analytic bi-univalent functions associated to the cardioid domain.

Univalency of Certain Transform of Univalent Functions

open access: yesProceedings of the Bulgarian Academy of Sciences, 2023
We consider univalency problem in the unit disc $$\mathbb{D}$$ of the function \[g(z)=\frac{(z/f(z))-1}{-a_{2}}, \] where $$f$$ belongs to some classes of univalent functions in $$\mathbb{D}$$ and $$a_{2}=\frac{f''(0)}{2}\neq 0$$.

On the Univalence of Poly-analytic Functions [PDF]

open access: yesComputational Methods and Function Theory, 2021
A continuous complex-valued function $F$ in a domain $D\subseteq\mathbf{C}$ is Poly-analytic of order $ $ if it satisfies $\partial^ _{\overline{z}}F=0.$ One can show that $F$ has the form $F(z)={\displaystyle\sum\limits_{0}^{n-1}}\overline{z}^{k}A_{k}(z)$, where each $A_k$ is an analytic function$.$ In this paper, we prove the existence of a Landau ...

Mapping properties of Janowski-type harmonic functions involving Mittag-Leffler function

open access: yesAIMS Mathematics, 2021
In this paper, we examine a connotation between certain subclasses of harmonic univalent functions by applying certain convolution operator regarding Mittag-Leffler function.

On Certain Properties of a Univalent Function Associated with Beta Function

open access: yesAbstract and Applied Analysis, 2022
Beta function has some applications in differential equations and other areas of sciences and engineering where certain definite integrals are used. However, its applications to univalent functions have not been explored based on the available literature.
