Study of Second Hankel Determinant for Certain Subclasses of Functions Defined by Al-Oboudi Differential Operator

open access: yesمجلة بغداد للعلوم, 2020
The concern of this article is the calculation of an upper bound of second Hankel determinant for the subclasses of functions defined by Al-Oboudi differential operator in the unit disc.

SOME VARIATIONS OF JANOWSKI TYPE FUNCTIONS ASSOCIATED WITH M-SYMMETRIC POINTS

open access: yesJournal of New Theory, 2016
In the present paper, we introduce a new subclass S m s (b, γ, A, B), of starlike functions with respect to m-symmetric points. Some basic properties, Integral representations, first Hankel determinant and convolution properties for the functions ...

Second Hankel Determinant for Analytic Functions Defined by Ruscheweyh Derivative

open access: yesInternational Journal of Analysis and Applications, 2015
Let S denote the class of analytic and univalent functions in the open unit disk D= {z:|z|<1} with the normalization conditions. In the present article an upper bound for the second Hankel determinant |a₂a₄-a₃²| is obtained for the analytic functions ...

Hankel continued fractions and Hankel determinants for $q$-deformed metallic numbers

open access: yes
Fix $n$ a positive integer. Take the $n$-th metallic number $ϕ_n=\frac{n+\sqrt{n^2+4}}{2}$ (e.g. $ϕ_1$ is the golden number) and let $Φ_n(q)$ be its $q$-deformation in the sense of S. Morier-Genoud and V. Ovsienko. This is an algebraic continued fraction which admits an expansion into a Taylor series around $q=0$, with integral coefficients.
