Stable least-squares space-time boundary element methods for the wave equation
Daniel Hoonhout, Richard Löscher, Olaf Steinbach +1
In this paper, we recast the variational formulation corresponding to the single layer boundary integral operator for the wave equation as a minimization problem…
Calderón Preconditioning for Acoustic Scattering at Multi-Screens
Kristof Cools, Carolina Urzúa-Torres
We propose a preconditioner for the Helmholtz exterior problems on multi-screens. For this, we combine quotient-space BEM and operator preconditioning. For a class of multi-screens…
Towards coercive boundary element methods for the wave equation
Olaf Steinbach, Carolina Urzúa-Torres, Marco Zank
In this note, we discuss the ellipticity of the single layer boundary integral operator for the wave equation in one space dimension. This result not only generalizes the well-know…
Full operator preconditioning and the accuracy of solving linear systems
Stephan Mohr, Yuji Nakatsukasa, Carolina Urzúa-Torres
Unless special conditions apply, the attempt to solve ill-conditioned systems of linear equations with standard numerical methods leads to uncontrollably high numerical error. Ofte…
