On variations of characteristic values of entire matrix pencils

نویسنده

چکیده

Entire matrix-valued functions of a complex argument (entire matrix pencils) are considered. Bounds for spectral variations of pencils are derived. In particular, approximations of entire pencils by polynomial pencils are investigated. Our results are new even for polynomial pencils. © 2005 Elsevier Inc. All rights reserved.

An Arithmetic for Matrix Pencils

We deene an algebra on matrix pencils that is a natural extension of sums, products and quotients of real numbers. The classical algebra of linear transformations may be regarded as a special case of the algebra of pencils. The sum and product deened here preserve right deeating subspaces. We show below that the matrix sign function and the inverse-free algorithms can be derived from an algebra...

Perturbation Theory for Rectangular Matrix Pencils Perturbation Theory for Rectangular Matrix Pencils

abstract The theory of eigenvalues and eigenvectors of rectangular matrix pencils is complicated by the fact that arbitrarily small perturbations of the pencil can cause them disappear. However, there are applications in which the properties of the pencil ensure the existence of eigen-values and eigenvectors. In this paper it is shown how to develop a perturbation theory for such pencils. ABSTR...

Parameter-Dependent Rank-One Perturbations of Singular Hermitian Or Symmetric Pencils

Structure-preserving generic low-rank perturbations are studied for classes of structured matrix pencils, including real symmetric, complex symmetric, and complex Hermitian pencils. For singular pencils it is analyzed which characteristic quantities stay invariant in the perturbed canonical form, and it is shown that the regular part of a structured matrix pencil is not affected by generic pert...

Fields of Values and Inclusion Regions for Matrix Pencils

We are interested in (approximate) eigenvalue inclusion regions for matrix pencils (A,B), in particular of large dimension, based on certain fields of values. We show how the usual field of values may be efficiently approximated for large Hermitian positive definite B, but also point out limitations of this set. We introduce four field of values based inclusion regions, which may effectively be...

Sensitivity and Perturbation analysis of Polynomial Eigenvalue problem

The conference dinner will take place in Café Campus behind the Mathematics Building on the campus of TU Berlin. We discuss a general framework for sensitivity and perturbation analysis of polynomial eigen-value problem. More specifically, we discuss first order variations of simple eigenvalues of matrix polynomials, determine the gradients and present a general definition of condition number o...
