[NA] Michiel Hochstenbach: 25+ years of nonnormality, a review

20 januari 2023 12:30 t/m 13:30 - Locatie: Snijderszaal (EWI, LB 01.010) | Zet in mijn agenda

We will review several aspects of nonnormal matrices: well-established concepts, recent developments, and open questions. Aspects that will be mentioned include eigenvector condition numbers, pseudospectra, field of values, scaling/balancing, shift invariancy, Krylov spaces, and two-sided methods. We will mention connections to some key scientific problems such as solving linear systems and eigenvalue problems, as well as some practical implementation tips.
