Sinc Methods for Domain Decomposition

, 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.

Analysis of a sinc-Galerkin Method for the Fractional Laplacian

, 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 ...

Analytical and Numerical Treatment of Evolutionary Time-Fractional Partial Integro-Differential Equations with Singular Memory Kernels

Fractal and Fractional
Evolution equations with fractional-time derivatives and singular memory kernels are used for modeling phenomena exhibiting hereditary properties, as they effectively incorporate memory effects into their formulation.

Approximation of weakly singular integral equations by sinc projection methods. ETNA - Electronic Transactions on Numerical Analysis

, 2020
In this paper, two numerical schemes for a nonlinear integral equation of Fredholm type with weakly singular kernel are studied. These numerical methods blend collocation, convolution, and approximations based on sinc basis functions with iterative ...

New Applications and Improvements of Sinc Functions for Solving a System of Fredholm Integral Equations

Axioms
This study introduces two novel methodologies for solving systems of Fredholm integral equations, with particular emphasis on second-kind equations. The first method integrates the Sinc-collocation technique with a newly developed singular exponential ...

An Application Of The Sinc-Collocation Method To A Three-Dimensional Oceanography Model

, 2013
In this paper, we explore the applicability of the Sinc- Collocation method to a three-dimensional (3D) oceanography model. The model describes a wind-driven current with depth-dependent eddy viscosity in the complex-velocity system. In general, the Sinc-based methods excel over other traditional numerical methods due to their exponentially decaying ...
