Frames for the solution of operator equations in Hilbert spaces with fixed dual pairing
Peter Balazs, Helmut Harbrecht
For the solution of operator equations, Stevenson introduced a definition of frames, where a Hilbert space and its dual are {\em not} identified. This means that the Riesz isomorph…
Boosting quantum machine learning models with multi-level combination technique: Pople diagrams revisited
Peter Zaspel, Bing Huang, Helmut Harbrecht +1
Inspired by Pople diagrams popular in quantum chemistry, we introduce a hierarchical scheme, based on the multi-level combination (C) technique, to combine various levels of approx…
A scalable H-matrix approach for the solution of boundary integral equations on multi-GPU clusters
Helmut Harbrecht, Peter Zaspel
In this work, we consider the solution of boundary integral equations by means of a scalable hierarchical matrix approach on clusters equipped with graphics hardware, i.e. graphics…
Multilevel quadrature for elliptic problems on random domains by the coupling of FEM and BEM
Helmut Harbrecht, Marc Schmidlin
Elliptic boundary value problems which are posed on a random domain can be mapped to a fixed, nominal domain. The randomness is thus transferred to the diffusion matrix and the loa…
