A Priori Error Estimates for the Optimal Control of the Integral Fractional Laplacian [PDF]

open access: yesSIAM Journal on Control and Optimization, 2019
We design and analyze solution techniques for a linear-quadratic optimal control problem involving the integral fractional Laplacian. We derive existence and uniqueness results, first order optimality conditions, and regularity estimates for the optimal variables.

A Priori Error Estimates for Mixed Finite Element Schemes for the Wave Equation

open access: yesSultan Qaboos University Journal for Science, 2015
A family of implicit-in-time mixed finite element schemes is presented for the numerical approximation of the acoustic wave equation. The mixed space discretization is based on the displacement form of the wave equation and the time-stepping method ...

Error estimates for approximating fixed points and best proximity points for noncyclic and cyclic contraction mappings [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2023
In this article, we find a priori and a posteriori error estimates of the fixed point for the Picard iteration associated with a noncyclic contraction map, which is defined on a uniformly convex Banach space with a modulus of convexity of power type.

A priori error estimates of regularized elliptic problems [PDF]

open access: yesNumerische Mathematik, 2020
AbstractApproximations of the Dirac delta distribution are commonly used to create sequences of smooth functions approximating nonsmooth (generalized) functions, via convolution. In this work we show a-priori rates of convergence of this approximation process in standard Sobolev norms, with minimal regularity assumptions on the approximation of the ...

On the fully discrete approximations of the MGT two-temperatures thermoelastic problem

open access: yesArchives of Mechanics, 2022
We consider a one-dimensional two-temperatures thermoelastic model. The corresponding variational problem leads to a coupled system which is written in terms of the mechanical velocity, the temperature speed and the inductive temperature.

Quasi-A Priori Truncation Error Estimation in the DGSEM [PDF]

open access: yesJournal of Scientific Computing, 2014
In this paper we show how to accurately perform a quasi-a priori estimation of the truncation error of steady-state solutions computed by a discontinuous Galerkin spectral element method. We estimate the spatial truncation error using the ?-estimation procedure.

Quasistatic Porous-Thermoelastic Problems: An a Priori Error Analysis

open access: yesMathematics, 2021
In this paper, we deal with the numerical approximation of some porous-thermoelastic problems. Since the inertial effects are assumed to be negligible, the resulting motion equations are quasistatic.

The Surrogate Matrix Methodology: A Priori Error Estimation [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
We give the first mathematically rigorous analysis of an emerging approach to finite element analysis (see, e.g., Bauer et al. [Appl. Numer. Math., 2017]), which we hereby refer to as the surrogate matrix methodology. This methodology is based on the piece-wise smooth approximation of the matrices involved in a standard finite element discretization ...
