An Energy Stable Discontinuous Galerkin Time-Domain Finite Element Method in Optics and Photonics
Asad Anees, Lutz Angermann
In this paper, a time-domain discontinuous Galerkin (TDdG) finite element method for the full system of Maxwell's equations in optics and photonics is investigated, including a com…

Error estimates for completely discrete FEM in energy-type and weaker norms
Lutz Angermann, Peter Knabner, Andreas Rupp
The paper presents error estimates within a unified abstract framework for the analysis of FEM for boundary value problems with linear diffusion-convection-reaction equations and b…
