A parallel solver for a preconditioned space-time boundary element method for the heat equation
Stefan Dohr, Michal Merta, Günther Of +2
We describe a parallel solver for the discretized weakly singular space-time boundary integral equation of the spatially two-dimensional heat equation. The global space-time nature…

Preconditioned space-time boundary element methods for the one-dimensional heat equation
Stefan Dohr, Olaf Steinbach
In this note we describe a space-time boundary element discretization of the heat equation and an efficient and robust preconditioning strategy which is based on the use of boundar…

A FEM for an optimal control problem subject to the fractional Laplace equation
Stefan Dohr, Christian Kahle, Sergejs Rogovs +1
We study the numerical approximation of linear-quadratic optimal control problems subject to the fractional Laplace equation with its spectral definition. We compute an approximati…
