Hermite–Hadamard–Fejér-Type Inequalities and Weighted Three-Point Quadrature Formulae

open access: yesMathematics, 2021
The goal of this paper is to derive Hermite–Hadamard–Fejér-type inequalities for higher-order convex functions and a general three-point integral formula involving harmonic sequences of polynomials and w-harmonic sequences of functions. In special cases,

Characterization of the generalized Chebyshev-type polynomials of first kind

open access: yesInternational Journal of Applied Mathematical Research, 2015
Orthogonal polynomials have very useful properties in mathematical problems, and in recent years there has been significant development in the field of approximation theory using orthogonal polynomials. In this paper, we characterize a sequence of generalized Chebyshev-type polynomials of the first kind {Tn(M,N)(x)}n∈N∪{0}\{T_n^{(M,N)}(x)\}_{n \in ...

The Chebyshev Polynomials Of The First Kind For Analysis Rates Shares Of Enterprises

open access: yes, 2023
Chebyshev polynomials of the first kind have long been used to approximate experimental data in solving various technical problems. Within the framework of this study, the dynamics of shares of eight Czech enterprises was analyzed by the Chebyshev polynomial decomposition: CEZ A.S. (CEZP), Colt CZ Group SE (CZG), Erste Bank (ERST), Komercni Banka (BKOM)

Nonlinear permuted Granger causality

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

A New Efficient Method for Solving System of Weakly Singular Fractional Integro-Differential Equations by Shifted Sixth-Kind Chebyshev Polynomials

open access: yesJournal of Mathematics, 2022
In this paper, a new approach for solving the system of fractional integro-differential equation with weakly singular kernels is introduced. The method is based on a class of symmetric orthogonal polynomials called shifted sixth-kind Chebyshev ...

Study on fracture parameter calibration and failure characteristics of rock with hole and crack

open access: yesDeep Underground Science and Engineering, EarlyView.
The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Solving Special Case of Inverse Sturm-Liouville Problem with Aftereffect by using Chebyshev Polynomials

open access: yesپژوهش‌های ریاضی, 2021
Introduction In this study, we consider the differential equation with aftereffect under the separated boundary conditions on a finite interval. In fact, we consider the Sturm-Liouville operator disorganized by a Volterra integral operator. We obtain the
