28 p, 297.4 KB A subspace correction method for discontinuous Galerkin discretizations of linear elasticity equations / Ayuso, B. ; Georgiev, Ivan ; Kraus, Johannes ; Zikatanov, Ludmil ; Centre de Recerca Matemàtica
We study preconditioning techniques for discontinuous Galerkin discretizations of isotropic linear elasticity problems in primal (displacement) formulation. We propose subspace correction methods based on a splitting of the vector valued piecewise linear discontinuous finite element space, that are optimal with respect to the mesh size and the Lamé parameters.

48 p, 405.8 KB Discontinuous Galerkin methods for the Multi-dimensional Vlasov-Poisson problem / Ayuso de Dios, Blanca (Centre de Recerca Matemàtica) ; Carrillo de la Plata, José Antonio (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Shu, C.-W. (Brown University. Division of Applied Mathematics) ; Centre de Recerca Matemàtica
We introduce and analyze two new semi-discrete numerical methods for the multi-dimensional Vlasov-Poisson system. The schemes are constructed by combing a discontinuous Galerkin approximation to the Vlasov equation together with a mixed finite element method for the Poisson problem. [...]

49 p, 515.7 KB Discontinuous Galerkin methods for the one-dimensional Vlasov-Poisson system / Ayuso de Dios, Blanca (Universidad Autónoma de Madrid. Departamento de Matemáticas) ; Carrillo de la Plata, José Antonio (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Shu, C.-W. (Brown University. Division of Applied Mathematics) ; Centre de Recerca Matemàtica
We construct a new family of semi-discrete numerical schemes for the approximation of the one-dimensional periodic Vlasov-Poisson system. The methods are based on the coupling of discontinuous Galerkin approximation to the Vlasov equation and several finite element (conforming, non-conforming and mixed) approximations for the Poisson problem.
