The coupled method for singularly perturbed Volterra integro-differential equations

open access: yesAdvances 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

open access: yes, 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

open access: yesJournal 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

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

open access: yesMathematical 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 ...

Superconvergence For Second Order Triangular Mixed And Standard Finite Elements

open access: yes, 1996
In this paper we will prove that both the second order Raviart-Thomas type mixed finite elements and the quadratic standard finite elements on regular and uniform triangular partitions, are superconvergent with respect to Fortin interpolation.

Generalized superconvergence relations for KN and scattering

open access: yes, 1968
Generalized superconvergence relations for KN and [Formula: see text] scattering are used to deduce parameters of the rho meson trajectory. Results are found to be in reasonable agreement with those from previous analyses using different methods.

Superconvergence effect in finite element methods for two-point boundary value problems [PDF]

open access: yes, 1987
.Approximate methods for solving two-point boundary value problems are considered. The aim of the paper is to explain superconvergence effect in the methods using finite element spaces.

Superconvergence of topological entropy in the symbolic dynamics of substitution sequences

open access: yesSciPost Physics, 2019
We consider infinite sequences of superstable orbits (cascades) generated by systematic substitutions of letters in the symbolic dynamics of one-dimensional nonlinear systems in the logistic map universality class.

Superconvergence of the iterated collocation methods for Hammerstein equations [PDF]

open access: yes, 1997
In this paper, we analyse the iterated collocation method for Hammerstein equations with smooth and weakly singular kernels. The paper expands the study which began in [16] concerning the superconvergence of the iterated Galerkin method for Hammerstein ...
