Preprint: Residual minimizing shift parameters for the low-rank ADI iteration


November 15th, 2018
A shift parameter generation technique for the low-rank ADI iteration for large Lyapunov equations is discussed, which is based on a residual minimization principle.

Preprint: A numerical comparison of solvers for large-scale, continuous-time algebraic Riccati equations


November 6th, 2018
In this survey article, Peter Benner, Zvonimir Bujanović (Uni Zagreb), Patrick Kürschner and Jens Saak present a extensive comparison of low-rank solvers for large-scale algebraic Riccati equations.
History of Lyapunov residuals and inner tolerances of (in)exact LR-ADI

Preprint: Inexact methods for the low rank solution to large scale Lyapunov equations


September 18th, 2018
Melina Freitag (Uni Bath) and Patrick Kürschner investigate the effect of inexact linear solves in rational Krylov subspace and low-rank ADI methods for large matrix equations. Dynamic stopping criteria are developed that decrease the amount of work spent in solving the sequences of linear systems.
