Computation of the canonical form for the matrices of chains and cycles of linear mappings

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/138099Paul Van Dooren [Linear Algebra Appl. 27 (1979) 103-140] constructed an algorithm for the computation of all irregular summands in Kronecker's canonical form of a matrix pencil. The algorithm is numerically stable since it uses only unitary transformations. We extend Paul Van Dooren's algorithm to the matrices of a cycle of linear mappings.34 pagesRepresentation Theory15A21; 15A22; 16G20Computation of the canonical form for the matrices of chains and cycles of linear mappingstext
