    Bounded rank perturbations of regular pencils over arbitrary fields 
    Baragana, Itziar; Dodig, Marija; Roca Martinez, Alicia; Stosic, Marko (Elsevier, 2020-09-15)
    [EN] In this paper we solve the bounded rank perturbation problem for regular pencils over arbitrary fields. The solution is obtained by reducing the problem to a row completion problem for matrix pencils. The result ...

    Pencils with prescribed constant subpencils 
    Roca Martinez, Alicia; Silva, Fernando (Elsevier, 2012-05-01)
    The results in this paper are within the scope of matrix pencil completion problems. Given an arbitrary matrix pencil, we obtain necessary and sufficient conditions for the existence of a strictly equivalent pencil with a ...

    Pencils with prescribed constant subpencils over arbitrary fields 
    Roca Martinez, Alicia; Silva, Fernando (Elsevier, 2014-03-15)
    Given an arbitrary matrix pencil, we obtain explicit necessary and sufficient conditions for the existence of a pencil strictly equivalent to it with a prescribed constant subpencil, for arbitrary fields. (C) 2013 Elsevier ...

    Rank-one perturbations of matrix pencils 
    Baragaña, Itziar; Roca Martinez, Alicia (Elsevier, 2020-12-01)
    [EN] 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 fields. (C) 2020 Elsevier Inc. All rights ...
