Decay bounds for Bernstein functions of Hermitian matrices with applications to the fractional graph Laplacian
Marcel Schweitzer
For many functions of matrices , it is known that their entries exhibit a rapid -- often exponential or even superexponential -- decay away from the sparsity pattern of the m…

A dimension-oblivious domain decomposition method based on space-filling curves
Michael Griebel, Marc Alexander Schweitzer, Lukas Troska
In this paper we present an algebraic dimension-oblivious two-level domain decomposition solver for discretizations of elliptic partial differential equations. The proposed paralle…

A fault-tolerant domain decomposition method based on space-filling curves
Michael Griebel, Marc-Alexander Schweitzer, Lukas Troska
We propose a simple domain decomposition method for -dimensional elliptic PDEs which involves an overlapping decomposition into local subdomain problems and a global coarse prob…
