Optimal Algebras and Novel Solutions of Time‐Fractional (2 + 1) − D European Call Option Model

open access: yesDiscrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
In this article, we analyse the time‐fractional (2 + 1) − D Black–Scholes model for European call options by employing Lie symmetry analysis. We derive the infinitesimal transformations and classify the optimal systems. Furthermore, under the geometric Brownian motion, we reduced the given model to ordinary differential equation (ODE) with integer ...

Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
A new method for constructing Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space is presented. In earlier research, we only dealt with scalar-valued weight functions.

Certain Constraints for Functions Provided by Touchard Polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
Since finding solutions to integral equations is usually challenging analytically, approximate methods are often required, one of which is based on Touchard polynomials. This paper examines the necessary constraints for the functions Ϝετς,Πε,τ,ςℏ, and the integral operator Lετς, defined by Touchard polynomials, to be in the comprehensive subclass ∁η(q3,

The Gegenbauer polynomials and typically real functions

open access: yesJournal of Computational and Applied Mathematics, 2003
Let \(T_R\) denote the class of functions \(f\) of the form \(f(z)=z +a_2z^2+ \cdots+ a_nz^n+ \dots\), \(z\in\mathbb{D}: =\{z:|z|0\) for \(z\in\mathbb{D} \setminus (-1,1)\) \textit{W. W. Rogosiński}, Math. Z. 35. 93-121 (1932; Zbl 0003.39303)]. The class \(T_R\) of typically real functions has been extended by \textit{J. Szynal} [Ann. Univ.

On a Class of Integrals Involving a Bessel Function Times Gegenbauer Polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
We provide information and explicit formulae for a class of integrals involving Bessel functions and Gegenbauer polynomials. We present a simple proof of an old formula of Gegenbauer.

Bi‐Starlike Function of Complex Order Involving Rabotnov Function Associated With Telephone Numbers

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
Telephone numbers defined through the recurrence relation Qn=Qn−1+n−1Qn−2 for n ≥ 2, with initial values of Q0=Q1=1. The study of such numbers has led to the establishment of various classes of analytic functions associated with them. In this paper, we establish two new subclasses of bi‐convex and bi‐starlike functions of complex order in the open unit

Continuous −1$-1$ hypergeometric orthogonal polynomials

open access: yesStudies in Applied Mathematics, Volume 153, Issue 3, October 2024.
Abstract The study of −1$-1$ orthogonal polynomials viewed as q→−1$q\rightarrow -1$ limits of the q$q$‐orthogonal polynomials is pursued. This paper presents the continuous polynomials part of the −1$-1$ analog of the q$q$‐Askey scheme. A compendium of the properties of all the continuous −1$-1$ hypergeometric polynomials and their connections is ...
