The coupled method for singularly perturbed Volterra integro-differential equations

Advances in Difference Equations, 2019
In this work a coupled (LDG-CFEM) method for singularly perturbed Volterra integro-differential equations with a smooth kernel is implemented. The existence and uniqueness of the coupled solution is given, provided that the source function and the kernel

Derivative superconvergence of linear finite elements by recovery techniques

, 2004
The aim of this article is to investigate the superconvergence in derivative approximations of finite element solutions. We construct three kinds of derivative recovery formulas at the mesh points for linear, bilinear and quadrilateral finite elements ...

Superconvergence Analysis of a Multiscale Finite Element Method for Elliptic Problems with Rapidly Oscillating Coefficients

Journal of Applied Mathematics, 2013
A new multiscale finite element method is presented for solving the elliptic equations with rapidly oscillating coefficients. The proposed method is based on asymptotic analysis and careful numerical treatments for the boundary corrector terms by virtue

An immediate analysis for global superconvergence for integrodifferential equations [PDF]

, 1997
summary:In this paper we study the finite element approximations to the parabolic and hyperbolic integrodifferential equations and present an immediate analysis for global superconvergence for these problems, without using the Ritz projection or its ...

Iterated Petrov–Galerkin Method with Regular Pairs for Solving Fredholm Integral Equations of the Second Kind

Mathematical and Computational Applications, 2018
In this work we obtain approximate solutions for Fredholm integral equations of the second kind by means of Petrov–Galerkin method, choosing “regular pairs” of subspaces, Xn,Yn, which are simply characterized by the positive definitiveness of a ...
