Linear maps preserving the Lorentz spectrum: The case
M. I. Bueno, Susana Furtado, Aelita Klausmeier +1
In this paper a complete description of the linear maps that preserve the Lorentz spectrum is given when and is the space of $n\tim…
Linearizations for interpolation bases -- a comparison I
A. Ashkar, Maria Isabel Bueno, R. Kassem +2
One strategy to solve a nonlinear eigenvalue problem is to solve a polynomial eigenvalue problem (PEP) that approximates the original problem through interpolat…
A comparison of eigenvalue condition numbers for matrix polynomials
Luis Miguel Anguas, María Isabel Bueno, Froilán M. Dopico
In this paper, we consider the different eigenvalue condition numbers for matrix polynomials used in the literature and we compare them. One of these condition numbers is a general…
Explicit block-structures for block-symmetric Fiedler-like pencils
Maribel Bueno Cachadina, Madeleine Martin, Javier Pérez +2
In the last decade, there has been a continued effort to produce families of strong linearizations of a matrix polynomial , regular and singular, with good properties. As a c…
