History

October 19 - October 25, 2003, Mathematisches Forschungsinstitut Oberwolfach

The mini-workshop was organized by Peter Benner (Chemnitz), Gene Golub (Stanford), Volker Mehrmann (Berlin) and Danny C. Sorensen (Houston). The main goal of this miniworkshop was to discuss different approaches for model order reduction of large-scale systems with special emphasis on numerical aspects of model reduction algorithms. There were 16 talks, informal discussion sessions and an open problems session. The topics included spectral projection model reduction methods, proper orthogonal decomposition method for optimal control problems, balanced truncation model reduction for linear systems in descriptor form and systems of second order, Krylov subspace methods for structured systems, controller reduction problems, passivity preserving model reduction techniques as well as different application areas for model reduction. It was decided to organize a benchmark collection of real-wold problems for use in comparative studies and testing of model order reduction algorithms. A proceedings book will also be published that will contain survey papers on problems posed during the mini-workshop and their solutions.
