Rank-one perturbations of matrix pencils

Itziar Baragaña, Alicia Roca

We solve the problem of characterizing the Kronecker structure of a matrix pencil obtained by a rank-one perturbation of another matrix pencil. The results hold over arbitrary fiel…

Fixed rank perturbations of regular matrix pencils

Itziar Baragaña, Alicia Roca

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 gener…
