This paper describes a set of rational filtering algorithms to compute a few eigenvalues (and
associated eigenvectors) of non-Hermitian matrix pencils. Our interest lies in computing …

In recent years, contour-based eigensolvers have emerged as a standard approach for the
solution of large and sparse eigenvalue problems. Building upon recent performance …

Power equipment is prone to vibrations. Removing eigenfrequencies of a structure from the
interval of working frequencies reduces the probability of resonance during operation. In this …

This thesis is concerned with improving and expanding projection based methods for
Hermitian interior eigenvalue problems. The focus is on methods of this type utilizing a …

Diese Dissertation beschäftigt sich mit der in Verbesserung von Material-wissenschaftlichen
Simulationen durch spezialisierte Subroutinen, sogenannte Kernel. Für jeden unserer …

We present a variant of the FEAST matrix eigensolver for solving restricted real and
symmetric eigenvalue problems. The method is derived from a combination of a variant of …
