On the Convergence of Ritz-Galerkin's Method

open access: yesPublications of the Research Institute for Mathematical Sciences, 1968
where D is a bounded domain in the (#, jO -plane, P is the boundary of D, and 0), &(:>0), c(>0), / are smooth functions defined on D. In Ritz-Galerkin's method, first we choose a system of linearly independent functions {^J such that they satisfy the given homogeneous boundary condition and they are dense in a function space containing the exact ...

A comparison between characteristic lines and streamline upwind Petrov-Galerkin method for advection dominated problems

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
This article develops numerically the advection-diffusion equation problem, using Galerkin on characteristic lines and Streamline Upwind Petrov-Galerkin (SUPG) methods. The dominated advective conditions in the solved problem showed that for cases where

Identifying Differential Equations by Galerkin's Method [PDF]

open access: yesMathematics of Computation, 1977
A numerical technique based on Galerkin’s method is presented for computing unknown parameters or functions occurring in a differential equation whose solution is known. Under certain conditions a solution can be shown to exist to the integral equation formulation of this problem. It is also shown that the resulting nonlinear system is nonsingular.

A Computational Study of an Implicit Local Discontinuous Galerkin Method for Time-Fractional Diffusion Equations

open access: yesAbstract and Applied Analysis, 2014
We propose, analyze, and test a fully discrete local discontinuous Galerkin (LDG) finite element method for a time-fractional diffusion equation. The proposed method is based on a finite difference scheme in time and local discontinuous Galerkin methods ...

Analysis of a Weak Galerkin Mixed Formulation for Modified Maxwell’s Equations

open access: yesMathematics
In this paper, we are interested in studying a mixed formulation of weak Galerkin type to approach the electric field and a Lagrange multiplier, which are solutions of a problem deriving from Maxwell’s equations.

Upper and Lower Bounds for Eigenvalues of the Elliptic Operator by Weak Galerkin Quadrilateral Spectral Element Methods

open access: yesAxioms
In this study, we investigate the upper- and lower-bound approximations of numerical eigenvalues derived by weak Galerkin spectral element methods on arbitrary convex quadrilateral meshes for the Laplace eigenvalue problem.
