MATRIX INTERVAL MONOTONICITY

open access: yes, 2010
We propose new notions of monotonicity for real matrices in order to characterize a particular notion of interval boundedness of various generalized inverses. AMS Subject Classification: 15A09, 15A48.

On nonnegative operators and fully cyclic peripheral spectrum

open access: yes, 1998
In this note the properties of the peripheral spectrumof a nonnegative linear operator A (for which the spectral radius is a pole of its resolvent) in a complex Banach lattice are studied.

Survey of power, QR, and iterative methods for solution of largest eigenvalue of essentially positive matrices

open access: yes, 2007
Many of the popular methods for the solution of largest eigenvalue of essentially positive irreducible matrices are surveyed with the hope of finding an efficient method suitable for electromagnetic engineering, radiation problems, system identification ...

Spectrum preserving lower triangular completions - the nonnegative nilpotent case

open access: yes, 1997
Nonnegative nilpotent lower triangular completions of a nonnegative nilpotent matrix are studied. It is shown that for every natural number between the index of the matrix and its order, there exists a completion that has this number as its index.

On the rate of convergence of the image space reconstruction algorithm

open access: yes, 2009
The Image Space Reconstruction Algorithm (ISRA) of Daube–Witherspoon and Muehllehner is a multiplicative algorithm for solving nonnegative least squares problems. Eggermont has proved the global convergence of this algorithm.
