Robust equilibrated a posteriori error estimators for the Reissner-Mindlin system
Emmanuel Creusé, Serge Nicaise, Emmanuel Verhille
We consider a conforming finite element approximation of the Reissner-Mindlin system. We propose a new robust a posteriori error estimator based on H(div) conforming finite element…
A posteriori error estimator based on gradient recovery by averaging for convection-diffusion-reaction problems approximated by discontinuous Galerkin methods
Emmanuel Creusé, Serge Nicaise
We consider some (anisotropic and piecewise constant) convection-diffusion-reaction problems in domains of R2, approximated by a discontinuous Galerkin method with polynomials of a…
A posteriori error estimates for a finite element approximation of transmission problems with sign changing coefficients
Serge Nicaise, Juliette Venel
We perform the a posteriori error analysis of residual type of a transmission problem with sign changing coefficients. According to [6] if the contrast is large enough, the continu…
Feedback boundary stabilization of wave equations with interior delay
K. Ammari, S. Nicaise, C. Pignotti
In this paper we consider a boundary stabilization problem for the wave equation with interior delay. We prove an exponential stability result under some Lions geometric condition.…
Stabilization of a piezoelectric system
K. Ammari, S. Nicaise
We consider a stabilization problem for a piezoelectric system. We prove an exponential stability result under some Lions geometric condition. Our method is based on an identity wi…
Analytic Regularity for Linear Elliptic Systems in Polygons and Polyhedra
Martin Costabel, Monique Dauge, Serge Nicaise
We prove weighted anisotropic analytic estimates for solutions of second order elliptic boundary value problems in polyhedra. The weighted analytic classes which we use are the sam…
