Optimal convergence rates in for a first order system least squares finite element method. Part I: homogeneous boundary conditions
Maximilian Bernkopf, Jens Markus Melenk
We analyze a divergence based first order system least squares method applied to a second order elliptic model problem with homogeneous boundary conditions. We prove optimal conver…
Caccioppoli-type estimates and -Matrix approximations to inverses for FEM-BEM couplings
Markus Faustmann, Jens Markus Melenk, Maryam Parvizi
We consider three different methods for the coupling of the finite element method and the boundary element method, the Bielak-MacCamy coupling, the symmetric coupling, and the John…
Approximating inverse FEM matrices on non-uniform meshes with -matrices
Niklas Angleitner, Markus Faustmann, Jens Markus Melenk
We consider the approximation of the inverse of the finite element stiffness matrix in the data sparse -matrix format. For a large class of shape regular but possibly…
