Fixed rank perturbations of regular matrix pencils

BARAGAÑA GARATE, ITZIAR; Roca Martinez, Alicia (Elsevier, 2020-03-15)

[EN] A characterization of the structure of a regular matrix pencil obtained by a bounded rank perturbation of another regular matrix pencil has been recently obtained. The result generalizes the solution for the bounded ...
Weierstrass Structure and Eigenvalue Placement of Regular Matrix Pencils under Low Rank Perturbations

Baragana Garate, Itziar; Roca Martinez, Alicia (Society for Industrial and Applied Mathematics, 2019)

[EN] We solve the problem of determining the Weierstrass structure of a regular matrix pencil obtained by a low rank perturbation of another regular matrix pencil. We apply the result to find necessary and sufficient ...
