Monomial Representations of Discrete Type of an Exponential Solvable Lie Group

Ali Baklouti, Hidenori Fujiwara, Jean Ludwig

Let G be an exponential solvable Lie group, H an analytic subgroup of G and χ a unitary character of H. We study some problems related to the induced representation τ=indGHχ of G when τ has multiplicities either finite or infinite of discrete type. In particular, we are interested in the Plancherel…

Comparing variational methods for the hinged Kirchhoff plate with corners

Colette De Coster, Serge Nicaise, Guido Sweers

The hinged Kirchhoff plate model contains a fourth order elliptic differential equation complemented with a zeroeth and a second order boundary condition. On domains with boundaries having corners the strong setting is not well‐defined. We here allow boundaries consisting of piecewise C2, 1‐curves…

A posteriori error estimates for a fully discrete approximation of Sobolev equations

Serge Nicaise, Fatiha Bekkouche

The paper presents an a posteriori error estimator for a (piecewise linear) conforming finite element approximation of some (linear) Sobolev equations in R d , d = 2 or 3, using implicit Euler's scheme. For this discretization, we derive a residual indicator, which uses a spatial residual…, L'accès aux articles de la revue « Confluentes Mathematici » (http://cml.cedram.org/), implique l'accord avec les conditions générales d'utilisation (http://cml.cedram.org/legal/).

Numerical resolution of some Helmholtz-type problems with impedance boundary condition or PML, Résolution numérique de quelques problèmes du type Helmholtz avec conditions au bord d'impédance ou des couches absorbantes (PML)

Jérôme Tomezyk

In this thesis, we propose wavenumber explicit convergence analyses of some finite element methods for time-harmonic Maxwell's equations with impedance boundary condition and for the Helmholtz equation with Perfectly Matched Layer (PML). We first study the regularized formulation of time-…, Dans cette thèse, nous étudions la convergence de méthode de type éléments finis pour les équations de Maxwell en régime harmonique avec condition au bord d'impédance et l'équation de Helmholtz avec une couche parfaitement absorbante(PML). On étudie en premier, la formulation régularisée…
