Applications of q-Borel distribution series involving q-Gegenbauer polynomials to subclasses of bi-univalent functions [PDF]

open access: goldHeliyon
This study introduces a new class of bi-univalent functions in the open disk using q-Borel distribution series and q-Gegenbauer polynomials. It provides estimates for the Taylor coefficients |μ2| and |μ3| for this family of functions, as well as ...

Weighted $$L^2$$-norms of Gegenbauer polynomials [PDF]

open access: greenAequationes mathematicae, 2022
We study integrals of the form \begin{equation*} \int_{-1}^1(C_n^{( )}(x))^2(1-x)^ (1+x)^ \, dx, \end{equation*} where $C_n^{( )}$ denotes the Gegenbauer-polynomial of index $ >0$ and $ , >-1$. We give exact formulas for the integrals and their generating functions, and obtain asymptotic formulas as $n\to\infty$.

A NEW EXTENSIONS OF GEGENBAUER POLYNOMIALS

open access: greenمجلّة جامعة عدن للعلوم الأساسيّة والتّطبيقيّة, 2020
The main aim of this paper is to introduce new extensions of Gegenbauer polynomials of one and two variables by using the extended Gamma function given by Chaudhry and Zubair [3]. Some properties of these extended polynomials such as generating functions,

New fractional-order shifted Gegenbauer moments for image analysis and recognition [PDF]

open access: yesJournal of Advanced Research, 2020
Orthogonal moments are used to represent digital images with minimum redundancy. Orthogonal moments with fractional-orders show better capabilities in digital image analysis than integer-order moments.

On the L 2 -norm of Gegenbauer polynomials. [PDF]

open access: yesMath Sci (Karaj), 2022
AbstractGegenbauer, also known as ultra-spherical, polynomials appear often in numerical analysis or interpolation. In the present text we find a recursive formula for and compute the asymptotic behavior of their $$L^2$$ L 2 -norm.

Mixed-Type Hypergeometric Bernoulli–Gegenbauer Polynomials

open access: yesMathematics, 2023
In this paper, we consider a novel family of the mixed-type hypergeometric Bernoulli–Gegenbauer polynomials. This family represents a fascinating fusion between two distinct categories of special functions: hypergeometric Bernoulli polynomials and ...

Fekete-Szegö Functional for Bi-univalent Functions Related with Gegenbauer Polynomials [PDF]

open access: goldJournal of Mathematics, 2022
In this paper, we introduce and investigate a new subclass of bi-univalent functions related with generating function of Gegenbauer polynomials. We will mainly find bounds on Maclaurin series coefficients for functions belonging to this class.

Fourier Series of Gegenbauer-Sobolev Polynomials [PDF]

open access: diamondSymmetry, Integrability and Geometry: Methods and Applications, 2018
We study the partial sum operator for a Sobolev-type inner product related to the classical Gegenbauer polynomials. A complete characterization of the partial sum operator in an appropriate Sobolev space is given. Moreover, we analyze the convergence of the partial sum operators.
