On the coupling of DPG and BEM
Thomas Führer, Norbert Heuer, Michael Karkulik
We develop and analyze strategies to couple the discontinuous Petrov-Galerkin method with optimal test functions to (i) least-squares boundary elements and (ii) various variants of…
DPG method with optimal test functions for a fractional advection diffusion equation
Vincent J. Ervin, Thomas Führer, Norbert Heuer +1
We develop an ultra-weak variational formulation of a fractional advection diffusion problem in one space dimension and prove its well-posedness. Based on this formulation, we defi…
A wirebasket preconditioner for the mortar boundary element method
Thomas Führer, Norbert Heuer
We present and analyze a preconditioner of the additive Schwarz type for the mortar boundary element method. As a basic splitting, on each subdomain we separate the degrees of free…
Local inverse estimates for non-local boundary integral operators
Markus Aurada, Michael Feischl, Thomas Führer +3
We prove local inverse-type estimates for the four non-local boundary integral operators associated with the Laplace operator on a bounded d-dimensional Lipschitz domain Omega for…
