Quasi-interpolation and a posteriori error analysis in finite element methods

approximation for the quasi-Stokes problem, which is based on the solution of local problem on stars with low cost computation, this indicator is equivalent to the energy error norm

Purpose  This paper aims at assessing the eect of (1) the statical admissibility of the recovered solution; (2) the ability of the recovered so- lution to represent the

Polynomial robust stability analysis for H(div)-conforming finite elements for the Stokes equations. Elliptic reconstruction and a posteriori error estimates for parabolic

In Farhloul and Manouzi [1], these authors have introduced a mixed finite el- ement method for problem (0.1) based on the introduction of σ = |∇ u | p − 2 ∇ u as a new unknown and

In this work we present robust a posteriori error estimates for a discretization of the heat equation by conforming finite elements and a classical A-stable θ -scheme, avoiding

In this work we propose and analyze two estimators (η and ˜ η) of residual type associated with two mixed finite element approximations of the two-dimensional frictionless

Under appropriate conditions (in particular if Γ is C ∞ ), it is asymptotically exact with respect to the Galerkin norm of the error in the sense that when the mesh is refined
