Generalizing Reduced Rank Extrapolation to Low-Rank Matrix Sequences
Pascal den Boef, Patrick Kürschner, Xiaobo Liu +5
Reduced rank extrapolation (RRE) is an acceleration method typically used to accelerate the iterative solution of nonlinear systems of equations using a fixed-point process. In thi…

Reduced rank extrapolation for multi-term Sylvester equations
Peter Benner, Pascal den Boef, Patrick Kürschner +2
We investigate the acceleration of stationary iterations for multi-term Sylvester equation by means of reduced rank extrapolation (RRE). Theoretical convergence results and impleme…

Stable Sparse Operator Inference for Nonlinear Structural Dynamics
Pascal den Boef, Diana Manvelyan, Joseph Maubach +2
Structural dynamics models with nonlinear stiffness appear, for example, when analyzing systems with nonlinear material behavior or undergoing large deformations. For complex syste…
