Adaptive space-time BEM for the heat equation with Neumann boundary conditions
Gregor Gantner, Helmut Harbrecht, Franz Nowakowsky
We consider the space-time boundary element method (BEM) for the heat equation with prescribed initial and Neumann data. We propose a weighted-residual a posteriori error estimator…

Elliptic PDEs on log-Gaussian Shapes: Sparsity and Finite Element Discretization
Dinh Dũng, Helmut Harbrecht, Van Kien Nguyen +1
In this article, we consider the solution to elliptic diffusion problems on a class of random domains obtained by log-Gaussian random homothety of the unit disk respectively an ann…
