Analysis of Spectral Tau Method for Approximate Solution of Fourth‐Order BVP in Hilbert Spaces

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This research explores the effectiveness of the spectral Tau method for solving fourth‐order differential boundary value problem (FBVP). We transform this FBVP into a Volterra–Fredholm integral equation (VFIE). By applying Banach’s fixed‐point theorem, we investigate the existence and uniqueness of the solution for the VFIE form of the FBVP equation ...

Sinc-Galerkin method and a higher-order method for a 1D and 2D time-fractional diffusion equations

open access: yesBoundary Value Problems
In this article, a new numerical algorithm for solving a 1-dimensional (1D) and 2-dimensional (2D) time-fractional diffusion equation is proposed. The Sinc-Galerkin scheme is considered for spatial discretization, and a higher-order finite difference ...

Modeling and Numerical Investigation of Space‐Fractional Advection Diffusion Models by Galerkin’s Weighted Residual Method

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this study, we first model the space‐fractional advection equation by choosing an exact solution under certain restrictions. Then, the forcing term is determined according to that solution. Secondly, we present a numerical solution for a class of space‐fractional advection‐diffusion equations with a nonlinear source term involving both time and ...

Symmetrization of the sinc-Galerkin method for boundary value problems [PDF]

open access: yesMathematics of Computation, 1986
The Sinc-Galerkin method developed in [5], when applied to the second-order selfadjoint boundary value problem, gives rise to a nonsymmetric coefficient matrix. The technique in [5] is based on weighting the Galerkin inner products in such a way that the method will handle boundary value problems with regular singular points.

Analyze Second‐Order PDEs Using the Volterra–Fredholm Integral Equation

open access: yesJournal of Function Spaces, Volume 2025, Issue 1, 2025.
In this study, we propose a novel approach to address a particular second‐order partial differential equation along with its boundary value conditions (SPDEs). In this process, we transfer the SPDEs problem into Volterra–Fredholm integral equation (VFIE), and we perform the Tau method bases on orthogonal Legendre polynomials directly, for solution of ...

A high‐order numerical method for solving non‐periodic scattering problems in three‐dimensional bi‐periodic structures

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 104, Issue 9, September 2024.
Abstract In this paper, we focus on scattering of non‐periodic incident fields in three‐dimensional bi‐periodic structures, as they can not be solved by the classical methods used for the quasi‐periodic scattering problems. To solve such non‐periodic scattering problems, the Floquet–Bloch transform, which decomposes the unbounded problem into a family ...

Application of Sinc-Galerkin Method for Solving Space-Fractional Boundary Value Problems [PDF]

open access: yesMathematical Problems in Engineering, 2015
We employ the sinc-Galerkin method to obtain approximate solutions of space-fractional order partial differential equations (FPDEs) with variable coefficients. The fractional derivatives are used in the Caputo sense. The method is applied to three different problems and the obtained solutions are compared with the exact solutions of the problems. These

Solving the first Painleve equation using the Sinc-Galerkin method

open access: yesInternational Journal of Applied Mathematical Research, 2012
The main goal of this paper is to solve the ?rst Painleve equation using the sinc-Galerkin method. In order to obtain this goal, we ?rst describe brie?y the sinc-Gelrkin method, and then we apply it to the ?rst Painleve equation. At last, the numerical result is shown to demonstrate the power and accuracy of the method.

Acoustic Green's Functions using the 2D Sinc-Galerkin Method

open access: yes, 2014
In many acoustic problems, the radiated sound field is dominated by scattering effects. Green's functions represent the scattering behaviour of a particular geometry and are required to propagate acoustic disturbances through complex geometries using integral methods.
