Error analysis of a weak Galerkin finite element method for two-parameter singularly perturbed differential equations in the energy and balanced norms
Toprakseven, Şuayip; Zhu, Peng (Elsevier, 2023)A weak Galerkin finite element method is proposed for solving singularly perturbed problems with two parameters. A robust uniform optimal convergence has been proved in the corresponding energy and a stronger balanced norms ... -
A parameter-uniform weak Galerkin finite element method for a coupled system of singularly perturbed reaction-diffusion equations
Toprakseven, Şuayip; Zhu, Peng (Faculty of Sciences and Mathematics, University of Nis, Serbia, 2023)The aim of this paper to investigate a weak Galerkin finite element method (WG-FEM) for solving a system of coupled singularly perturbed reaction-diffusion equations. Each equation in the system has perturbation parameter ... -
Uniform convergent modified weak Galerkin method for convection-dominated two-point boundary value problems
Toprakseven, Şuayip; Zhu, Peng (Scientific Technical Research Council Turkey-Tubitak, 2021)We propose and analyze a modified weak Galerkin finite element method (MWG-FEM) for solving singularly perturbed problems of convection-dominated type. The proposed method is constructed over piecewise polynomials of degree ...
