ON THE INVARIANT FACES ASSOCIATED WITH A CONE-PRESERVING MAP [PDF]
, 1998 For an n×n nonnegative matrix P , an isomorphism is obtained between the lattice of initial subsets (of {1, · · · , n}) for P and the lattice of P -invariant faces of the nonnegative orthant R+.

Lattice-ordered matrix algebras over real GCD-domains
, 2012 Let $ R \subset \R $ be a GCD-domain. In this paper, Weinberg's conjecture on the $ n \times n $ matrix algebra $ M_{n}(R) \ (n \geq 2) $ is proved. Moreover, all the lattice orders (up to isomorphisms) on a full $ 2 \times 2 $ matrix algebra over $ R ...

A note on infinite extreme correlation matrices [PDF]
, 2006 We give a characterization for the extreme points of the convex set of correlation matrices with a countable index set. A Hermitian matrix is called a correlation matrix if it is positive semidefinite with unit diagonal entries.

A polynomial time spectral decomposition test for certain classes of inverse M-matrices
, 1998 The primary result in this paper is a set of O(n) time algorithms to determine whether a speci ed real, symmetric matrix is a member of any of several closely related classes: the MMA-matrices; the inverse MMA-matrices; the strictly positive, positive de

Extremal copositive matrices with minimal zero supports of cardinality two
, 2017 Let $A \in {\cal C}^n$ be an extremal copositive matrix with unit diagonal. Then the minimal zeros of $A$ all have supports of cardinality two if and only if the elements of $A$ are all from the set $\{-1,0,1\}$.

, 2012 Pisot numbers, primitive matrices and beta-conjugates. We show that given a Pisot number β, for any integer n large enough, there is a nonnegative primitive square matrix whose order is equal to the degree of β, and the matrix admits β for eingenvalue ...

Extensions of inequalities involving Kantorovich constant
, 2011 In this paper, two methods of extending inequalities involving Kantorovich constant are presented. An inequality of Micic et al. [Linear Algebra Appl., 318 (2000), 87–107] on positive linear maps and geometric mean of positive definite matrices is ...

, 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.

Inverse elementary divisor problems for nonnegative matrices
, 2011 The aim of this paper is to answer three questions formulated by H. Minc in his two papers and book on the problem of prescribed elementary divisors for entrywise nonnegative or doubly stochastic matrices.

On nonnegative operators and fully cyclic peripheral spectrum
, 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.
