Bounds On The Extreme Eigenvalues Of Real Symmetric Toeplitz Matrices

, 2000
We derive upper and lower bounds on the smallest and largest eigenvalues, respectively, of real symmetric Toeplitz matrices. The bounds are first obtained for positive-definite matrices and then extended to the general real symmetric case. Our bounds are

On the Laplacian index of tadpole graphs

Special Matrices
In this article, we study the Laplacian index of tadpole graphs, which are unicyclic graphs formed by adding an edge between a cycle Ck{C}_{k} and a path Pn{P}_{n}.

An Implicitly Restarted Symplectic Lanczos Method for the Symplectic Eigenvalue Problem

, 1998
. An implicitly restarted symplectic Lanczos method for the symplectic eigenvalue problem is presented. The Lanczos vectors are constructed to form a symplectic basis.

The hyperbolic CS decomposition of tensors based on the C-product

Open Mathematics
This paper studies the issues about the hyperbolic CS decomposition of tensors under the C-product. The aim of this paper is fourfold. Firstly, we establish the CS decomposition of a complex unitary tensor, including the thin version and the standard ...

Markov Chain Sensitivity Measured By Mean First Passage Times

, 1999
The purpose of this article is to present results concerning the sensitivity of the stationary probabilities for a n-state, time-homogeneous, irreducible Markov chain in terms of the mean first passage times in the chain. Key words.

Block diagonalization of (p, q)-tridiagonal matrices

Special Matrices
In this article, we study the block diagonalization of (p,q)\left(p,q)-tridiagonal matrices and derive closed-form expressions for the number and structure of diagonal blocks as functions of the parameters pp, qq, and nn. This reduction enables efficient

If A Matrix Has Only A Single Eigenvalue How Sensitive Is This Eigenvalue? II

, 1998
. For matrices with a single eigenvalue the sensitivity of the eigenvalue to perturbations in the matrix is analyzed. Simple bounds are derived that separate the influence of the index on the eigenvalue sensitivity from the influence of the non-normality.
