Eigenvalues, Pseudospectrum and Structured Perturbations
We investigate the behavior of eigenvalues under structured perturbations. We show that for many common structures such as (complex) symmetric, Toeplitz, symmetric Toeplitz, circulant and others the structured condition number is equal to the unstructured condition number for normwise perturbations, and prove similar results for real perturbations. An exception are complex skewsymmetric matrice...
متن کاملA Note on Computing Eigenvalues of Banded Hermitian Toeplitz Matrices
It is pointed out that the author's O(n 2) algorithm for computing individual eigenvalues of an arbitrary n × n Hermitian Toeplitz matrix T n reduces to an O(rn) algorithm if T n is banded with bandwidth r.
متن کاملA Note on Graphs with Exactly Two Main Eigenvalues
In this note, we consider connected graphs with exactly two main eigenvalues. We will give several constructions for them, and as a consequence we show a family of those graphs with an unbounded number of distinct valencies.
متن کاملA note on unimodular eigenvalues for palindromic eigenvalue problems
We consider the occurrence of unimodular eigenvalues for palindromic eigenvalue problems associated with the matrix polynomial Pn(λ) ≡ ∑n i=0Aiλ i where Ai = An−i with M∗ ≡ M , M or PMP (P 2 = I). From the properties of palindromic eigenvalues and their characteristic polynomials, we show that eigenvalues are not generically excluded from the unit circle, thus occurring quite often, except for ...
متن کاملA Note on Eigenvalues of Perturbed Hermitian Matrices
Let A = ( H1 E ∗ E H2 ) and à = ( H1 O O H2 ) be Hermitian matrices with eigenvalues λ1 ≥ · · · ≥ λk and λ̃1 ≥ · · · ≥ λ̃k, respectively. Denote by ‖E‖ the spectral norm of the matrix E, and η the spectral gap between the spectra of H1 and H2. It is shown that |λi − λ̃i| ≤ 2‖E‖ η + √ η2 + 4‖E‖2 , which improves all the existing results. Similar bounds are obtained for singular values of matrices u...
