We construct the Hasse diagrams G 2 and G 3 for the closure ordering on the sets of
congruence classes of 2× 2 and 3× 3 complex matrices. In other words, we construct two …

Stratification of controllability and observability pairs—Theory and use in applications

E Elmroth, S Johansson, B Kågström - SIAM journal on matrix analysis and …, 2009 - SIAM
Cover relations for orbits and bundles of controllability and observability pairs associated

Reduction and normal forms of matrix pencils

O Verdier - arXiv preprint arXiv:1205.1138, 2012 - arxiv.org
Matrix pencils, or pairs of matrices, may be used in a variety of applications. In particular, a
pair of matrices (E, A) may be interpreted as the differential equation E x'+ A x= 0. Such an …
