Sinc-Galerkin method for solving linear sixth-order boundary-value problems [PDF]

open access: yesMathematics of Computation, 2003
A Galerkin method to solve linear sixth-order boundary-value problems is proposed. As basis functions the so-called Sinc-functions are used. These functions are advantageous for problems with singularities. The linear system to compute the unknown coefficients is developed using an appropriate inner product.

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 ...

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.

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.
