Applications of differential subordination

open access: yesApplied Mathematics Letters, 2006
In this paper the authors use the techniques of differential subordinations in the complex plane and that of convolution, to introduce certain subclasses of analytic functions on the unit disk. In particular, they obtain various subclasses of analytic functions that have been previously investigated by Padmanabhan and Parvatham; Padmanabhan and Manjini,

Strong Differential Subordinations and Superordinations for Riemann–Liouville Fractional Integral of Extended q-Hypergeometric Function

open access: yesMathematics, 2023
The notions of strong differential subordination and its dual, strong differential superordination, have been introduced as extensions of the classical differential subordination and superordination concepts, respectively.

Fuzzy Differential Subordination Associated with a General Linear Transformation

open access: yes, 2023
In this study, we investigate a possible relationship between fuzzy differential subordination and the theory of geometric functions. First, using the Al-Oboudi differential operator and the Babalola convolution operator, we establish the new operator ...

Some Special Differential Subordinations

open access: yesHacettepe Journal of Mathematics and Statistics, 2018
Summary: For an analytic function \(p\) satisfying \(p(0) = 1\), we obtain sharp estimates on \(\beta\) such that the first order differential subordination \(p(z) + \beta zp'(z) \prec \mathcal{P}(z)\) or \(1 + \beta zp'(z)/p^j(z) \prec \mathcal{P}(z)\), \(j = 0,1,2\) implies \(p(z) \prec \mathcal{Q}(z)\) where \(\mathcal{P}\) and \(\mathcal{Q}\) are ...

Differential subordination and argumental property

open access: yesComputers & Mathematics with Applications, 2008
AbstractFor analytic functions f(z) in the open unit disk E and convex functions g(z) in E, Ch. Pommerenke [Ch. Pommerenke, On close-to-convex analytic functions, Trans. Amer. Math. Soc. 114 (1) (1965) 176–186] has proved one theorem which is a generalization of the result by K. Sakaguchi [K. Sakaguchi, On a certain univalent mapping, J. Math.

Applications of differential subordinations involving a generalized fractional differintegral operator

open access: yesJournal of Inequalities and Applications, 2019
Using the third-order differential subordination basic results, we introduce certain classes of admissible functions and investigate some applications of third-order differential subordination for p-valent functions associated with generalized fractional

Application of Pythagorean means and Differential Subordination

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2022
For $0\leqα\leq 1,$ let $H_α(x,y)$ be the convex weighted harmonic mean of $x$ and $y.$ We establish differential subordination implications of the form \begin{equation*} H_α(p(z),p(z)Θ(z)+zp'(z)Φ(z))\prec h(z)\Rightarrow p(z)\prec h(z), \end{equation*} where $Φ,\;Θ$ are analytic functions and $h$ is a univalent function satisfying some special ...
