Modified Sinc-Galerkin Method for Nonlinear Boundary Value Problems [PDF]

open access: yesJournal of Mathematics, 2013
This paper presents a modified Galerkin method based on sinc basis functions to numerically solve nonlinear boundary value problems. The modifications allow for the accurate approximation of the solution with accurate derivatives at the endpoints.

Analysis of a sinc-Galerkin Method for the Fractional Laplacian

open access: yesSIAM Journal on Numerical Analysis, 2023
We provide the convergence analysis for a sinc-Galerkin method to solve the fractional Dirichlet problem. This can be understood as a follow-up of an earlier article by the same authors, where the authors presented a sinc-function based method to solve fractional PDEs.

Sinc-Galerkin method for solving nonlinear boundary-value problems

open access: yesComputers and Mathematics With Applications, 2004
This paper deals with nonlinear ordinary differential equations of \(2m\)th-order \((m= 1,2,3)\), \[ u^{(2m)}+ r(x) uu'+ k(x) H(u)= f(x),\quad 0\leq x\leq 1, \] subject to the boundary conditions \(u^{(j)}(0)= 0\), \(u^{(j)}(1)= 0\), \(0\leq j\leq m-1\), where \(H(u)\) may be a polynomial or a rational function, or exponential.

Sinc-Galerkin method for solving the time fractional convection–diffusion equation with variable coefficients

open access: yesAdvances in Difference Equations, 2020
In this paper, a new numerical algorithm for solving the time fractional convection–diffusion equation with variable coefficients is proposed. The time fractional derivative is estimated using the L 1 $L_{1}$ formula, and the spatial derivative is ...

Sinc-Galerkin estimation of diffusivity in parabolic problems [PDF]

open access: yesInverse Problems, 1993
Summary: A fully sinc-Galerkin method for the numerical recovery of spatially varying diffusion coefficients in linear parabolic partial differential equations is presented. Because the parameter recovery problems are inherently ill-posed, an output error criterion in conjunction with Tikhonov regularization is used to formulate them as infinite ...

Solving nonlinear boundary value problems by the Galerkin method with sinc functions

open access: yesOpen Physics, 2015
In this paper, the sinc-Galerkin method is used for numerically solving a class of nonlinear differential equations with boundary conditions. The importance of this study is that sinc approximation of the nonlinear term is stated as a new theorem.
