Recent developments of the Sinc numerical methods

open access: yesJournal of Computational and Applied Mathematics, 2004
This paper gives a survey of recent developments of the Sinc numerical methods. A variety of Sinc numerical methods have been developed by Stenger and his school. For a certain class of problems, the Sinc numerical methods have the convergence rates of O(

Solving two-dimensional fuzzy Fredholm integral equations via sinc collocation method

open access: yesAdvances in Difference Equations, 2020
In this paper, we present a numerical method to solve two-dimensional fuzzy Fredholm integral equations (2D-FFIE) by combing the sinc method with double exponential (DE) transformation.

The Sinc-collocation method for solving the Thomas–Fermi equation

open access: yes, 2013
A numerical technique for solving nonlinear ordinary differential equations on a semi-infinite interval is presented. We solve the Thomas–Fermi equation by the Sinc-Collocation method that converges to the solution at an exponential rate.

Finite Difference and Sinc-Collocation Approximations to a Class of Fractional Diffusion-Wave Equations

open access: yesJournal of Applied Mathematics, 2014
We propose an efficient numerical method for a class of fractional diffusion-wave equations with the Caputo fractional derivative of order α. This approach is based on the finite difference in time and the global sinc collocation in space.

Sinc Methods for Domain Decomposition

open access: yes, 2008
Sinc basis functions form a desirable basis to use for solving singular problems via domain decomposition. This is because both the Sinc-Galerkin and sinc-collocation-methods converge exponentially, even in the presence of boundary singularities.
